A body of mass 4kg falls from a height 5m, calculate a.The potential energy at the top?

The potential energy of an object is given by the equation:

Potential Energy = mass * acceleration due to gravity * height

Given:

Mass (m) = 4 kg

Height (h) = 5 m

Acceleration due to gravity (g) = 9.8 m/s^2 (approximate value on Earth)

Calculating the potential energy:

Potential Energy = 4 kg * 9.8 m/s^2 * 5 m

Potential Energy = 196 J

Therefore, the potential energy of the object at the top (5 meters high) is 196 Joules.
