Q. 3. A boy standing at the top of a tower of 20 m height drops a stone. Assuming g = 10 ms2, the velocity with Which it hits the ground is
(1) 5.0 m/s (2) 10.0 m/s
(3) 20.0 m/s (4) 40.0 m/s

Answer : (3)
Q. 4. A person of mass 60 kg is inside a lift of mass 940 kg and presses the button one control panel. The lift starts moving upwards with an acceleration 1.0ms-2. If g = 10 ms^(-2), the tension in the supporting cable is :
(1) 1200 N (2) 8600 N
(3) 9680 N (4) 11000 N
Sol:
T = (M + m) (g + a) = (940 + 60) (10 + 1) = 11000 N
Answer (4)
Q. 5. A body projected vertically from the earth reaches a height equal to earth's radius before returning to the earth. The power exerted by the gravitational force is greatest

(2) At the highest position of the body
(3) At the instant just before the body hits the earth
(4) It remains constant all through
Sol:
Just before hitting q is zero and both F, Vare maximum.
Answer (3)
