Question

A 4.00 kg stone is dropped from a height of 145 m. What is the stone’s potential and kinetic energy respectively when it is 50.0 m from the ground?

A - 1,960 J, 5,680 J



B - 5,680 J, 1,960 J



C - 3,720 J, 1,950 J



D - 1,960 J, 3,720 J

Answer 1

C - 3,720 J, 1,950 J

Step-by-step explanation:

Hello

Epotential = M*G*H

Ep = (4)(9.8)(145-50)

Ep = 3729 J

Then

Ec = 1950 J
