A mass of 0.5 kg moving with a speed of 1.5 m/s on horizontal smooth surface, collides with a nearly weightless spring of force constant k = 50 N/m. The maximum compression of the spring would be [figure]
(1) 0.15 m
At maximum compression the whole kinetic energy is stored in the spring:
12mv2 = 12kx2
x = v mk = 1.5 0.550
= 1.5 0.1 = 0.15 m
Answer: (1)
When a long spring is stretched by 2 cm, its potential energy is U. If the spring is stretched by 10 cm, the potential energy stored in it will be
A stone is tied to a string of length l and is whirled in a vertical circle with the other end of the string as the centre. At a certain instant of time, the stone is at its lowest position and has a speed u. The magnitude of the change in velocity as it reaches a position where the string is horizontal (g being acceleration due to gravity) is
If kinetic energy of a body is increased by 300% then percentage change in momentum will be :
250 N force is required to raise 75 kg mass from a pulley. If the rope is pulled 12 m, then the load is lifted 3 m. The efficiency of the pulley system will be
A child is sitting on a swing. Its minimum and maximum heights from the ground are 0.75 m and 2 m respectively, its maximum speed will be
Two springs A and B having spring constant KA and KB (KA = 2KB) are stretched by applying force of equal magnitude. If energy stored in spring A is EA, then energy stored in B will be
A man is slipping on a frictionless inclined plane and a bag falls down from the same height. Then the velocity of both is related as
If F = (60 i + 15 j - 3 k) N and v = (2 i - 4 j + 5 k) m/s, then instantaneous power is
As shown in the figure at point O a mass is performing vertical circular motion. The average velocity of the particle is increased, then at which point will the string break [figure]
