Question

In order to raise a mass m a man ties it to a rope and passes the rope over a frictionless pulley. He climbs the
rope with an acceleration 3g/2 relative to the rope. If the mass of the man is m/2 and the mass of the rope is
negligible, the tension in the rope is​

Answer 1

Answer:

Explanation:

let acceleration of rope is a

then acceleration of man = a+ 3g/2

applying equation for mass m

mg-t = ma

applying equation for m/2 mass

t-mg/2 = m/2(a+ 3g/2)

mg/2 = 3ma/2 + 3mg/4

g = 3a + 3g/2
