a light inextensible rope with a load of 90 kilogram tied at one end is passed over a smooth fixed Pulley a man of mass 60 kilogram holding at the other end climbs up with the acceleration 3 by 2 relative to the rope in order to raise the load the tension in the string is​

Answer 1

332/ms in air conditioning system is the best way of spreading the word

Answer 2

Answer:

1260N

Explanation:

Let a be the accelaration of the rope and T the tension. For the rising rope

T-90g = 90a

For the man,

T-60g= 60(3/2 g-a)

Solving,

T=90×7/5 g

=1260 N
