A ball thrown up vertically returns to the thrower after 6 (c ) its position after 4 s.

A body of mass of 2 kg moving with velocity 4 ms^( -1) horizontally stops after 2 s. If the body is to be kept in motion at the same surface with 4 ms^(-1) force needed is :

A spherical shell of mass 20 kg is stationary at the top of a hill of height 100 m. It rolls down a smooth surface to the ground, then climbs up another hill of height 30 m and finally rolls down to a horizontal base at a height of 20 m above, the ground. The velocity attained by the ball is :

A bolt of mass 0.3 kg falls from the ceiling of an elevator moving down with an uniform speed of 7 ms^(-1) . It hits the floor of the elevator (length of the elevator = 3m) and does not rebound. What is the heat produced by the impact? Would your answer be different if the elevator were stationary?

Two blocks m_(1)=1kg , m_(2)=2kg are placed one upon the other. m_(1) is kept on m_(2) . The force of static friction between m_(1) and m_(2) is 0.2 and between m_(2) and the horizontal surface and the floor is 0.28 . Calculate the maximum force that can be applied on m_(2) so that m_(1) and m_(2) does not get separated. (g=10ms^(-2))
