Question

A man of mass 50 kg jumps to a height of 1m. His potential energy at the height point is(g =10m/s2)

Answer 1

Answer:

M1 = 50 kg

h = 1m

Ep = mgh

Ep = 50 X 10 X 1

Ep = 500

therefore potential energy is 500

Answer 2

Answer:

His potential energy is 500 joule.

Explanation:

• Potential energy has to do with position,in stead of speed.
• A particle of mass m at a height difference h from has gravitational energy to be mgh where g is the gravitational acceleration
• Now,we put the values in the formula/
• m=50Kg,g= $10ms^{-2}$ ,h=1m
• Thus, potential energy is $50 \times 10 \times 1$=500J.

Therefore,the potential energy of the man at the height is 500J.
