1. A tray is moved horizontally back and forth in simple harmonic motion at a frequency of f=2.00Hz. on this tray is an empty cup. obtain the coefficient of static friction between the tray ad cup given that the cup begins slipping when the amplitude of the motion is 0.05m 2. f=kx...

can someone pls provide me with a mathematical representation of the previous replies? or at least outline the steps that i will need to follow im a bit confused about all this thnx ty

i found the center of mass but i am not sure how to incorporate that into the problem and then how i can resolve the vectors pls help

1. a solid sphere (I=0.4mr^2) of mass 1.5 kg and radius 15 cm moves down a 35 degrees incline 7m long. Assuming it started from rest, what is its angular velocity in rad/s at the bottom of the incline? a)71.27 b)32.25 c)49.98 d)61.69 3.i tried by plugging in the values and trying to...

1. A uniform 5m ladder of mass 12kg rests against a wall with its base 3m from the wall. A painter of mass 55kg sits 3.5m of the way up the ladder. what is the horizontal force in N exerted on the ladder by the wall? a)110.45 b)178.45 c)232.67 d)327.08 in the previous problem what is the...

i kno tht the horizontal component is fcos29 however i don't seem to be able to get to the force im completely lost ty

thnx alot can u help me with my other problems? ty

i have already made the drawing however i am not sure how to separate it into its components also how do you mathematically express the horizontal component to the frictional force? and for part b it is just the horizontal component ty

ok i will try thnx

so i would substitute 4m/s into the v part of the equation? ty

isnt PE = mgh? im not sure if i am making this more complicated or is there anything to do with circular motion? ty

doesnt the velocity remain the same? or does it change due to gravity? this is confusing ty

the drawing shows a version of the loop the loop trick for a small car. if the car is given an initial velocity of 4m/s what is the largest value that the radius r r can have if the car is to remain in contact with the circular track at all times? please refer to the attached file for a diagram...

work & energy; please help! i need some guidance on how to go about solving this one: a water slide is constructed so that swimmers, starting from rest at the top of the slide leave the slide traveling horizontally. A person hits the water 5.00m from the end of the slide in a time of 0.5sec...

work & energy; please help! i have this one problem in my homework tht i cannot solve: A person pushes a 16kg cart at a constant velocity for a distance of 22.0m. She pushes in a direction 29 degrees below the horizontal. A 48 N frictional force opposes the motion of the cart. a) what is the...
