About ELASTIC collisions: (both questions are related to each other.) Please answer it short and easy to understand What happens if the cars have the same mass but one car has twice the velocity? If one car has twice the mass as the second car, can you still get the cars to bounce back equally? Explain how.
6. A block of mass m, = 5.0 kg is released from a height of 5.0 m (point A) down a smooth, curved ramp. It makes an elastic head-on collision with a block of mass m; = 10 kg that is initially at rest. (a) What is the maximum height reached by m, after the collision? (b) After the collision, m2 glides smoothly until it hits a rough patch and eventually comes to a stop. What is the length of the rough patch if the coefficient of kinetic friction between m, and the rough patch is 0.350?
a block with a mass of 0.5 kg is released from rest on a frictionless track at a distance 2.5m above the top of the table. it then collides elastically with an object having mass m2=1.0kg that is initially at rest on the table as shown in the figure. the table is h2=2.oo m . a)How far away from the bottom of the table do the objects land ? Hints : determine the velocities just after the collision . how high does object 1 travel back up the track. b) suppose the collision is inelastic , where does combined object land please see attached image
