1. A block falls from a table 0.6 m high. It lands on an ideal, mass-less, vertical spring with a force constant of 2.4 kN/m. The spring is initially 25 cm high, but it is compressed to a minimum height of 10 cm before the block is stopped. Find the mass of the block (g = 9.81 m/s2).
(A) 55.51 kg
(B) 5.51 kg
(C) 0.51 kg
(D) None

2. An engine pumps water continuously through a hose. If the speed with which the water passes through the hose nozzle is v, and if k is the mass per unit length of the water jet as it leaves the nozzle, what is the rate at which kinetic energy is being imparted to the water ?
(A) 12 kv2
(B) 12 kv3
(C) 12 kv4
(D) None

3. n identical light bulbs, each designed to draw power P from a certain voltage supply are joined in series across that supply. The total power which they will draw, is
(A) nP
(B) P
(C) P/n
(D) Pn–2

4. One mole of an ideal gas is at temperature T oK. The γ value of this gas is 5/3. Now the gas does 12R Joules of work adiabatically (R is the universal gas constant). Then the final temperature of the gas will be
(A) (T – 8) o K
(B) (T + 4) o K
(C) (T – 4.4) o K
(D) (T – 6) o K

5. A light ladder is supported on a rough floor and leans against a smooth wall, touching the wall at height ‘h’ above the floor. A man climbs up the ladder until the base of the ladder is on the verge of slipping. The coefficient of static friction between the foot of the ladder and the floor is µ. The horizontal distance moved by the man is
(A) µ2h
(B) µ/h
(C) µh
(D) µ2h2

6. A disk of 10 cm radius has a moment of inertia of 0.02 kg.m2. A force of 15 N is applied tangentially to the periphery of the disk to give it an angular acceleration, α of magnitude
(A) 25 µ/h rad/s2
(B) 35 µ/h rad/s2
(C) 45 µ/h rad/s2
(D) 75 rad/s2

7. A uniform hollow cylinder has a density ρ, a length ‘L’, an inner radius ‘a’, and an outer radius ‘b’. Its moment of inertia about the axis of the cylinder is (Mass of the cylinder is‘M’)
(A) M(b2+ a2)
(B) 2M(b2 + a2)
(C) M2 (b2 + a2)
(D) 3M4 (b2+ a2)

8. The two wires A and B of the same material have their lengths in the ratio 1 : 2 and their diameters in the ratio 2 : 1. If they are stretched with the same force, the ratio of the increase in the length of A to that of B will be
(A) 1 : 2
(B) 4 : 1
(C) 1 : 8
(D) 1 : 4
