Question

A clay ball (mass = 0.25kg) has a rightward momentum of +1.75 kg∙m/s. A second clay ball (mass = 0.25 kg) has a leftward momentum of -1.75 kg∙m/s. The two collide, stick together, and come to a complete stop after the collision.What was the total energy of the system after the collision?6.13 J12.25 JNot enough information to determine0 J

Answer 1

Kinetic energy = 1/2 m v ^2

Where:

m= mass

v= speed

Since after the collison, v = 0 (stop)

Total energy after the collision = 0 J
