A body moves with an initial Velocity of 2 m/s and acce-
lerated uniformly to attain
a Velocity of 5 m/s after
5 sec, it maintan a uniform
Velocity for 3sec before
decelerating after
another 2 sec,
sketch The Velocity graph
and calculate

1. Accelanation of the body
2. Deccelaration of the body
3. Total dis lance travelled​

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
