1.Rotational Dynamics

A horizontal circular platform of masss M is rotating at angular velocity Omega about a vertical axis passing through its centre. A boy of mass m is standing at the edge of the platform. If the boy comes to the centre of the platform, then the new angular velocity becomes

1.Rotational Dynamics

Two bodies rotate with kinetic energies. K1 and K2 movement of inertia about their axis of rotation, is I1 and I 2. If I1=3*I2 and K1=27 K2 then the ratio of their angular momenta I1 to I2 is

1.Rotational Dynamics

A disc of Mars 50KG and radius 1m is rotating at 180 rpm. The torque required to rotate the disc in opposite direction with the same speed in 24 seconds is

1.Rotational Dynamics

A particle moves along a circle of radius R with constant tangential acceleration. If the velocity of the particle is V at the end of second revolution from the start, then the tangential acceleration is

1.Rotational Dynamics

A body is just revolved in a vertical circle of radius R, when the body is at the highest point, the string breaks. The horizontal distance covered by the body after the string breaks is

1.Rotational Dynamics

The radius of gyration of a solid sphere of radius R and Mass M about its diameter is Kd and about the tangent of a solid sphere is Kt. The ratio of Kt to Kd is

1.Rotational Dynamics

A weightless thread can bear a tension upto 3.7 kg-wt. A stone of mass 500 g is tied to it andrevolved in a circular path of radius 4 m in a vertical plane. If g=10 ms^-2, then the maximum angular velocity of the stone will be:

1.Rotational Dynamics

A road is 10 metre wide. Its radius of curvature is 50 metres. The outer edge is above the inner edge by a distance of 1.5 metres. This road is most suited for velocity

1.Rotational Dynamics

A particle of mass M performs uniform circular motion of radius R with linear speed V under the application of Force F. If M, V and R are all increased by 50% then necessary change in force required to maintain the particle in uniform circular motion is
