: Question 8 The Following Two Questions Refer To This Problem A Block Of Mass 10 Kg Is Moving On A Horizontal Frictionle 2 (29.35 KiB) Viewed 43 times

QUESTION 8 The following two questions refer to this problem: A block of mass 10 kg is moving on a horizontal frictionless surface with a speed of 6 m/s towards a block (at rest) with a mass of 20 kg. Take the positive direction to be the direction that the 10 kg block is initially moving. If these blocks collide in a perfectly inelastic collision, what is their final velocity?
QUESTION 9 If the blocks collide in an elastic collision, what is the velocity of the 10 kg block after the collision? Hint: You will have to solve two equations and two unknowns for an elastic collision.
