Question

A person does work equal to 2500J in climbing a tree of heigh 5m. what is the mass of person?​

Answer 1

Work done = 2500 J

Distance = 5m

The Angle of most the tree is = 90°

Formula,

Work done = force(F) X distance(d)

putting values,

2500 J = F X 5m

F = 2500/5

F = 500N

Hence, the mass of the person is 50kg
