A light inextensible string that gas over a smoth fixed polley as shown in the figure connect two blocks of mases it `0.36` kg and `0.72` kg Taking `g = 10 ms^(-2)` , find the work done by the string on the block of mass ` 0.36` kg doring the first second after the system is released from rest ,

Text Solution

Verified by Experts

The correct Answer is:
`(8)`
`2mg-T=2ma`

`T-mg=ma`
`a=g/3`
`T=(4mg)/(3)`
`W=Txxs=Txx1/2 at^2=8J`

The two blocks in an Atwood machine have masses 2.0 kg and 3.0 kg. Find the work done by gravity during the fourth second after the system is released from rest.

A ring of mass m = 0.3kg can slide freely on smooth vertical rod. A light and inextensible string is connected to the ring and passes over a smooth and fixed pulley as shown in the figure. The distance of the pulley from the rod is 0.8m and the other end of the string is connected to a block of mass M = 0.5kg. The ring is held in level with pulley and then released from rest. The distance by which the ring moves down before coming to rest for the first time is 0.75K. Find K.

Two blocks are connected by a massless string that passes over a frictionless peg as shown in figure. One end of the string is attached to a mass m_1=3kg , i.e., a distance R=1.20m from the peg.
