Question

You drop a 5 kg ball from a height of 2 m. Just

before it reaches the ground, how much kinetic
energy does it have?

Answer 1

Kinetic energy = 98 N

Step-by-step explanation:

Given:

Mass = 5 kg

Height = 2 m

Find:

Kinetic energy

Computation:

K(e) = P(e)

So,

P(e) = mgh

So,

K(e) = (5)(9.8)(2)

Kinetic energy = 98 N
