A ladder is hanging from ceiling as shownin figure. Three men A, B and C of masses 40 kg, 60 kg, and 50 kg are climbing the ladder. Man A is going up with retardation `2m//s^(2),` C is going up with an acceleration of `1m//s^(2)` and man B is going up with a constantg speed of `0.5` m/s. Find the tension in the string supporting the ledder. `[g=9.8m//s^(2)]`

A 1kg stone at the end of 1m long string is whirled in a vertical circle at a constant speed of 4m//s . The tension in the string is 6N , when the stone is at (g=10m//s^(2))

A balloon os mass 2 KG is rising up with an acceleration of 4m/s^2 . The upward force acting on the balloon is (g = 10 ms^-2)

Suppose the ceiling in the previous problem is that the elevator which is going up with an acceleration of 2.0 m/s^2 . Find the elongations.

A mass of 1kg is suspended by a thread. It is 1. lifted up with an accleration 4.9 m//s^(2) . 2. lowered with an acceleration 4.9 m//s^(2) . The ratio of the tensions is

A lift of mass 100 kg is moving upwards with an acceleration of 1 m//s^(2) . The tension developed in the string, which is connected to lift is ( g=9.8m//s^(2) )
