Question

A ball weighs around 1 kg and s traveling at 20 meters per second, what is its kinetic energy?​

Answer 1

Answer:

My dear friend

If you want more explanation then reply back

Explanation:

Kinetic energy =1/2×m×V^2

Kinetic energy =1/2×1×20×20

=20J

Answer 2

Answer:

KE = 1/2 * m * v2

KE = 1/2 * 1kg * (20 m /s)2

KE = 200 J

3. A boy weighs 50 kg and is running 3 meters per second, what is his kinetic energy?

KE = 1/2 * m * v2

KE = 1/2 * 50 kg * (3 m/s)2

KE = 225 J
