A 50 kg ball traveling at 20 m/s would have

kinetic energy

A 50 kg ball traveling at 5 m/s would have

W kinetic energy

A 50 kg person falling at 10 m/s would have

kinetic energy.

1) 4 times more

2) 4 times less

3) The same

Step-by-step explanation:

I just know cause I'm smart plus I forget what I did in my head

The person below me is wrong by the way unless they want the actual answer to the problem

A : 10000 J

B: 625 J

C: 2500 J

Step-by-step explanation:

Step 1:

We know that,

Kinetic Energy is given by ((1/2) * m * V²) J

where m = Mass of substance

V = Velocity

Step 2:

In first case, m = 50 kg, V=20 m/s

Kinetic energy = 0.5 * 50 * 20 * 20

= 10000 J

In second case, m = 50 kg, V=20 m/s

Kinetic energy = 0.5 * 50 * 5 * 5

= 625 J

In Third case, m = 50 kg, V=10 m/s

Kinetic energy = 0.5 * 50 * 10 * 10

= 2500 J
