Kinetic Energy During Inelastic Collision

APPHMC-EOWDWV

A 3.0 kg lump of clay is moving to the left at 4.0 m/s. It collides in a perfectly inelastic collision with a 6.0 kg lump of clay moving to the right at 2.0 m/s.

What is the total kinetic energy after the collision?

A

$62 J$

B

$36 J$

C

$25 J$

D

$12 J$

E

$0 J$
