Three bodies A, B and C have equal kinetic energies and their masses are 400 g, 1.2 kg and 1.6 kg respectively. The ratio of their linear momenta is :
(1) 1 : 3 : 2
p = 2mK; K same ⇒ p m
pA : pB : pC = 0.4 : 1.2 : 1.6
= 1 : 3 : 4 = 1 : 3 : 2
Answer: (1)
[figure] A block is simply released from the top of an inclined plane as shown in the figure above. The maximum compression in the spring when the block hits the spring is :
A bullet of mass 50 g is fired with a speed 100 m/s on a plywood and emerges with 40 m/s. The percentage loss of kinetic energy is :
Four particles A, B, C, D of mass m2, m, 2m, 4m, have same momentum, respectively. The particle with maximum kinetic energy is :
When kinetic energy of a body becomes 36 times of its original value, the percentage increase in the momentum of the body will be :
A body of mass 50 kg is lifted to a height of 20 m from the ground in the two different ways as shown in the figures. The ratio of work done against the gravity in both the respective cases, will be : [figure]
A body is moving unidirectionally under the influence of a constant power source. Its displacement in time t is proportional to :
If a rubber ball falls from a height h and rebounds upto the height of h/2. The percentage loss of total energy of the initial system as well as velocity of ball before it strikes the ground, respectively, are :
A body of m kg slides from rest along the curve of vertical circle from point A to B in frictionless path. The velocity of the body at B is: [figure] (given, R = 14 m, g = 10 m/s2 and 2 = 1.4)
A simple pendulum of length 1 m has a wooden bob of mass 1 kg. It is struck by a bullet of mass 10-2 kg moving with a speed of 2 102 ms-1. The bullet gets embedded into the bob. The height to which the bob rises before swinging back is : (use g=10 m/s2)
A body of mass 2 kg begins to move under the action of a time dependent force given by F= (6t i+6t2 j ) N. The power developed by the force at the time t is given by:
