    Max Ratio of Particle Mass to Bowl Mass for No Slide

    A hemispherical bowl of mass M rests on a table. The inside surface of the bowl is frictionless, while the coefficient of friction between the bottom of the bowl and the table is μ = 1. A particle of mass m (and negligible size) is released from rest at the top of the bowl and slides down into...

    Calculating Acceleration on a Slide with Kinetic Friction

    At a playground, a child slides down a slide that makes a 42° angle with the horizontal direction. The coefficient of kinetic friction for the child sliding on the slide is 0.20. What is the magnitude of her acceleration during her sliding? Ok so I tried to use the equation ax=-Uk*g to find the...

    Distance Covered by Puck A at Collision

    Two hockey pucks, labeled A and B, are initially at rest on a smooth ice surface and are separated by a distance of 18.0 . Simultaneously, each puck is given a quick push and they begin to slide directly toward each other. Puck A moves with a speed of = 2.70 , and puck B moves with a speed of...

    Why a slide rule is better than a computer

    Why a slide rule and pad of paper is better than a computer 1. A Slide Rule doesn't shut down abruptly when it gets too hot. 2. One hundred people all using Slide Rules and Paper Pads do not start wailing and screaming simultaneously due to a single-point failure (on the other hand, 100...

    Calculating Cork Volumes for Amusement Park Water Slide

    An amusement park is planning to build a water slide, and the park owners would like to use giant corks with density 0.28 g/cm^3 as "floats" for young children. What volume of cork is needed to keep 20% (by volume) of a 40 kg child above the water at the base of the slide (assuming the density...

    Solving for Speed, Height of Boy on Water Slide

    A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling horizontally. As Figure 3 below shows, a 50 kg boy is observed to hit the water 7 meters from the end of the slide, as shown. The slide is frictionless. Also, ignore...

    Solve Water Slide Problem: Initial Speed 0.54m/s, Height 3.2m

    "If the height of the water slide is h = 3.2m and the person's initial speed at point A (at the top of slide) is 0.54m/s, at what location does the swimmer splash down in the pool?" I need help with this guys. It may be relatively easy, but I'm not seeing it. I don't know what formula to...

    Calculating Distance Using Work-Energy Theorem

    I am stuck on the last problem for my homework. It seems to me like the problem doesn't have enough information to complete. I'd really appreciate any tips. A car traveling along a level road as a speed V slams on the brakes and skids to a stop. If the force of friction on the car is...

    Magnetic field, current, and a slide wire

    Hi, I really need help with this question. Here's the question: "The figure shows a U-shaped conducting rail that is oriented vertically in a horizontal magnetic field. The rail has no electric resistance and does not move. A slide wire with mass m and resistance R can slide up and down...

    Calculating Work and Coefficient of Kinetic Friction for a Sliding Seal

    I've been doing this problem for the last 170 minutes. Literally, and I'm pissed. A 43-kg seal at an amusement park slides from rest down a ramp into the pool below. The top of the ramp is 1.75 m higher than the surface of the water and the ramp is inclined at an angle of θ = 35.0° above the...

    Kinematics of wooden box on slide

    Can I have some tips on where to start this problem? I have no work because I can see no work to do. "A wooden box is placed on the left end of a 3.60-m long plywood ramp. The left end of the ramp is raised until the box begins to slide. What is the magnitude of the acceleration of the box...

    Sound coming out of slide whistle

    A slide whistle has a length of 27 cm. if you want ot play a note one octave higher the whistle should be how long? Ans : 1/2 lambda = L there Lambda = 2L = (2)(27) = 54 m is that correct?

    Block can slide along a table where the coefficient of friction

    A 198g wood block is firmly attached to a very light horizontal spring, as shown in the figure below. The block can slide along a table where the coefficient of friction is 0.287. A force of 23.1 N compresses the spring 17.7 cm. If the spring is released from this position, how far...

    What is the tension in a child's neck while sliding down a water slide?

    A child is lying on her back. The tension in the muscles of her neck is 55N as she raises her head to look past her toes and out the motel window. Ten minutes later she is screaming and sliding feet first down a water slide at a constant speed of 5.7 m/s in a horizontal curve of radius 2.40 m...

    Calculating Time it Takes for Soap to Slide Down a Ramp

    A wet bar of soap slides freely down a ramp 9.35 m long inclined at 7.00°. How long does it take to reach the bottom? Assume muk = 0.0550. Okay I've got my x & y componants 9.35cos(7)=9.28 9.35sin(7)=1.14 But now what since I don't have the mass of the soap or the acceleration, what do I...

    Calculate the coefficient of kinetic friction between the slide and the child

    A child slides down a slide with a 28° incline, and at the bottom her speed is precisely one half what it would have been if the slide had been frictionless. Calculate the coefficient of kinetic friction between the slide and the child. here's the two equations I used: sin28*m*g=m(v2/t)...

    Baseball player slide Friction problems

    Heres what the book gives: A baseball player slides into third base with an initial speed of 7.90m/s. If the coefficient of kinetic friction between the player and the ground is 0.41, how far does the player slide before coming to rest. Help? Please? :mad:

    Modeling Angled Slide Flight with SUVAT Equations

    For my mechanics, I am trying to model the flight of an objected released from an angled slide, which slides (not rolls) down a distance L (constant), launches at a hight h (constant) above ground and travels a distance X, until it hits the ground. The slide's angle A is adjusted. My...
