Question

A 20 kg cart travelling to the right at 10 m/s collides head- on with a 10 kg cart travelling 6 m/s to the left. After

the collision, the 10 kg cart is travelling 8 m/s to the right. a) What is the velocity of the 20 kg cart after the

collision? b) Determine wheter or not the collision is elastic (Show your calculations). c) Discuss whether or not

your answers to parts a) and b) are reasonable. Include specific reasons why you think the answers are or are

not reasonable.

You must show all work, starting with the equations on the front page, to recieve credit.

Here are equations on the first page:

p = mv; PE = mgh; KE = (1/2)mv2; P= W/t; W= Fdcos(theta); F = ( p/ t);

A hockey puck, mass 0.24 kg, travelling with a speed of +20 m/s. collides with another stationary puck of exactly half the mass, hitting it head-on, but instant superglue makes the pucks stick together. The collision is perfectly inelastic and one dimensional. Ignore any friction with the ice they are travelling on. Calculate the total momentum of the two-puck system both before and after the collision.
