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.
B. KE at 10 m/s > KE at 5 m/s
C. KE at 10 m/s < KE at 5 m/s
D. KE at 10 m/s = KE at 5 m/s

Answer 1

Here. This will help you find your answer.

Kinetic Energy:

Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

Step-by-step explanation:

So, this means you answer is option B.

Answer 2

B.KE at 10 m/s > KE at 5 m/s

Step-by-step explanation:

The faster the ball the more kinetic energy it has than potential
