Blocks A and B are moving toward each other.A has a mass of 2.0 kg and a velocity of 50 m/s, while B has a mass of 4.0 kg and a velocity of -25 m/s.They suffer a completely inelastic collision.The kinetic energy lost during the collision is:
A)0 J
B)1250 J
C)3750 J
D)5000 J
E)5600 J

Question

Quizplus · Accepted Answer

In a completely inelastic collision, the two objects stick together. The initial kinetic energy is 3750 J, and the final kinetic energy is 0 J, so the kinetic energy lost is 3750 J.
