One end of a massless rope, which passes...

One end of a massless rope, which passes over a massless and frictionless pulley P is tied to a hook C while the other end is free. Maximum tension that the rope can bear is 360 N. With what value of maximum safe acceleration (in `ms^-2`) can a man of 60kg climb on the scope?

Text Solution

Verified by Experts

The correct Answer is:
`4`
If a is acceleration of man climbing down the rope then as is clear from
`ma = mg - T`
`60 a = 60 xx 10 -360 =240`
`a = (240)/(60) = 4m//s^(2)`
