Question

A man of mass 30 kg uses a rope to climb which bears only 450N what is the maximum acceleration with which he can climb safely

Answer 1

the answer is 15m/s². the explanation is in the above picture.

Answer 2

Answer:

a=5m/s2

Explanation:

m=30kg

man is climbing so tection force applied

T=450N

man is climbing up

so T-mg=ma

450-30×10=30×a. (g=10m/s2)

450-300=30×a

150=30×a

a=150/30

a=5m/s2
