Ques 1 )The v-t graph of a moving object is shown:
1 velocity of the body at point C
2 accelaration acting on the body between A and B
3 accelaration acting on the body between B and C
4 total distance covered from A to D
The graph between the resistive force F acting on a body and the distance covered by the body is shown in the figure. The mass of the body is 25 kg and initial velocity is 2 m/s. When the distance covered by the body is 5m, its kinetic energy would be
A body of mass m is immersed in water with 3/4th of volume outside of water. Buoyant force acting on it is 1000N. Total volume of body is
( Take density of water as 1000kg/m3 and accelaration due to gravity as 10m/s2)
