Question

How much is the mass of a man if he has to do 2500J of work in climbing a tree 5m tall?? ​

Answer 1

Answer:

Mass of man =m

Height of tree , h=5m

Work done, W=2500J

Acceleration due to gravity , g=10m/s ^2

W=mgh

m= W/gh

m=50kg

Explanation:

Mass of man = m

Height of tree, h = 5m

Work done, W = 2500J

Acceleration due to gravity, g = 10 m/s2

W = mgh

m = W/gh

m = 50 kg.
