A light rope fixed to a peg on the ground passes over a tree branch and hangs on the other side A man weighing 60 kg wants to climb up the rope. If the peg comes out of the ground by a vertical force greater than `(360 sqrt(3))` N, with what maximum acceleration can the man climb up safely ? `(g=10m//s^(2))`

Text Solution

Verified by Experts

The correct Answer is:
`2m//s^(2)`
`T cos 30^(@) = 360 sqrt(3)`

`T=720N`
as man climbs up
`T-Mg=Ma`
`720-600=60xxa`
`a=120/60=2m//sec^(2)`
