    How Does Elastic Collision Affect Thomas the Tank Engine and Diesel?

    I meant for Part D that the energy was in transition between both train carts. Similar to how a spring contains the some of the energy being transferred while one cart is giving and the other is receiving. Part E I see what you mean with the difference being 15 N between each distance. And...

    How Does Elastic Collision Affect Thomas the Tank Engine and Diesel?

    Part D - It would then be somewhere in between the touching metal of the train cars about to be transferred ? Part E - 15 N acting at each impulse. And I think it is kinetic energy or work under the graph. Part F - The minimum distance is .03m right ?

    How Does Elastic Collision Affect Thomas the Tank Engine and Diesel?

    Part C - I take the vf from Part B and sub it into the formula for EK and use the total mass of both trains. EK = .5mv2 = .5(7.5 kg)( .4 m/s)2 = .6 J Part D - F - I have no clue. Help ?

    How Does Elastic Collision Affect Thomas the Tank Engine and Diesel?

    Thomas the tank engine and Diesel are involved in an elastic collision. A 2.5 kg Thomas is at rest but is approached head-on by a 5.0 kg Diesel moving at 0.60 m/s. The force-separation graph for the ensuing collision is given. FYI I am terrible with graphs, IDK WHY.. :frown: mT =...

    How Fast Can an Insect Travel on a CD Without Slipping Off?

    A .5g insect rests on a compact disc at a distance of 4cm from the centre. If the coeffiecient of static friction is .51 what is the maximum velocity the insect can experience without slipping off? I am lost, can someone help ?

    No, it isn't smart guy. 5a + 7.35 =/= 5a - 7.35

    Another Double Check FBD String Tension

    Calculate the tension in the cable connecting the two masses. Assume all surfaces are frictionless. FBD m1 = 5 kg θ1 = 60° m2 = 6 kg θ2 = 70° Equation 1 ~ FT - Fg = ma FT - mgSinθ = ma FT = 5a + 5(9.8)Sin60 FT = 5a + 42.44 Equation 2 ~ Fg - FT = ma...

    Need a Double Check / Verification

    In the following diagram there is a coefficient of friction, μ, of 0.15 between the 5.0 kg mass and the surface. Calculate the tension in the cable connecting the two masses and the resulting acceleration. FBD m1= 2 kg m2= 5 kg μ= .15 g= 9.8 m/s2 Equation 1 ~ Fg - FT = FN...

    Sniper Projectile Motion: Trajectory and Impact Analysis

    Alright, so assuming everything so far is correct, my only issue has been the angle at which the bullet hits the ground. If Tan θ = O / A then could I use the components for Sin and Cos ? My text says that I should change the Velocity of the Vertical Component by using: Vr = Vy + aΔt...

    Sniper Projectile Motion: Trajectory and Impact Analysis

    First off, doesn't a Muzzle Velocity seem a bit low at 120 m/s? -_- Alright, so it looks like I end up with a Quadratic and solve for both values. 0 = -4.9t^2 + 60t + 35 t = -.55s and 12.8s But there can't be negative time, amiright ? And I am unsure about the Total change in the...

    Sniper Projectile Motion: Trajectory and Impact Analysis

    A sniper fires a bullet at 120 m/s at 30° above the horizontal from the roof top of a 35 m high parking garage. If the bullet strikes the level ground beside the parking garage: How long was the bullet in the air? How far from the base of the parking garage did the bullet land? At what...
