Question

Compare the kinetic energies of a ball moving at 5 m/s to when it is moving
at 10 m/s.
O A. The answer cannot be determined.
O B. KE at 10 m/s > KE at 5 m/s
O C. KE at 10 m/s < KE at 5 m/s
D. KE at 10 m/s = KE at 5 m/s

Answer 1

Answer:

B

Explanation:

KE = mv²/2

The more velocity (speed) is, the more kinetic energy an object has.

Because 10 m/s > 5 m/s,  KE at 10 m/s > KE at 5 m/s.
