A 70 kg man climbs 4 meters up a tree whats his potential energy relative from the ground

Potential energy of the man relative to the ground can be calculated by using the formula,

P. E = mgh

Here, m is the mass of the man = 70 kg

g is acceleration due to gravity = 9.8 m/s²

h = height above the ground = 4 m

Substituting the value we get,

Potential energy of the man = 70*9.8*4 = 2744 J
