Question

An object of mass 40 kg raised to a height of 5m above the ground. what is the potential energy ? object allowed to fall,find its kinetic energy of an object.​

Answer 1

Answer:

It's 1960 J

EXPLANATION:

Assumptions:

Mass 40Kg

Height 5m

Acceleration due to gravity (g) 9.8m/s

P.E = mgh

P.E = 40×9.8×5

P.E = 1960

According to law of conservation of energy:

Total P.E = K.E

= 1960J
