Question

A man of mass 50 kg jumps to a height of 1 M what will be his potential energy at the highest point where gravity is equals to 10 metre per second square

Answer 1

Given:

A man of mass 50 kg jumps to a height of 1 M  

To find:

What will be his potential energy at the highest point where gravity is equals to 10 metre per second square

Solution:

From given, we have,

The mass of a man = m = 50 kg

The height from where the man jumps = h = 1 m

The gravitational constant = g = 10 m/s^2

We use the formula,

Potential energy, P.E = m × g × h

P.E = 50 × 10 × 1 = 500 J

Therefore, the potential energy of a man at the highest point is 500 J
