Suppose an object that has a mass of 8.8 kg and slides on ice at a speed of 13 m/s. It runs into another object, which is initially at rest and has a mass of 11.10 kg. They naturally stick together (in a perfectly elastic colision). What is their final velocity in (m/s)?

A 160 kg merry-go-round has a radius of 2.5 m and it is rotating with an angular velocity of 0.7 rev/s. What is its angular velocity after an at rest 86-kg person gets onto it by grabbing its outer edge?

A bloke of mass 5 kg slides along an ice rink with a velocity of 3 m/s. It strikes another block of mass 4 kg in a perfectly elastic collision sending the second block sliding along the ice. The second block them collides with a third block with a massive 5 kg. Assuming to find a collision is perfectly elastic what is the velocity of the final block

Beginning from rest, an object of mass 200 kg slides down a 9-m-long ramp. The ramp is inclined at an angle of 20o from the horizontal. Air resistance and friction between the object and the ramp are negligible. Let g = 9.81 m/s2. Determine the kinetic energy of the object, in kJ, and the velocity of the object, in m/s, at the bottom of the ramp.

A mass m = 78 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 15.4 m and finally a flat straight section at the same height as the center of the loop (15.4 m off the ground). Since the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it must be released above the top of the...
