Question
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 60 kg climb on the rope ?
Options
A.16
B.6
C.4
D.9.8
Solution
T - 60 g = 60 a; T = 3000 N ; ∴ a = 4 ms-2
