Question

on climbing a tree up to 8 m high the work done by a person is 1200J. what is the mass of the person?​

Answer 1

Explanation:

In this case,

work done = mass × gravitational force× height

1200 = mass × 9.8×8

mass = 1200/9.8×8

mass 1200/78.4

= 15.306 kg

if u take the value of g = 10m/s²

then mass = 1200/80 = 15kg
