A weightless thread can bear tension upto 3.7 kg wt. A stone of mass 500 gms is tied to it and revolved in a circular path of radius 4 m in a vertical plane. If

g = 10\;m{s^{ - 2}}

, then the maximum angular velocity of the stone will be

View answer and explanation

Correct option: A

4 radians/sec

Option A (4 radians/sec) is correct because it is the maximum angular velocity calculated by equating the tension at the lowest point to the maximum tension the string can bear.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
