Asked by Zane
Two objects moving with a speed v travel in opposite directions in a straight line. The objects stick together when they collide, and move with a speed of v/10 after the collision.
(a) What is the ratio of the final kinetic energy of the system to the initial kinetic energy?
1/100 [Your answer is correct.]
(b) What is the ratio of the mass of the more massive object to the mass of the less massive object?

b) You can solve this from the conservaton of momentum equation
Mv-mv=(M+m)v/10
.9M=1.1m
solve for M/m
check my math.
Mv-mv=(M+m)v/10
.9M=1.1m
solve for M/m
