In previous problem, if initially the platform with the child is rotating with an angular speed `omega_(1)`. If child start walking along its periphery in opposite direction with speed u relative to platform, what will be the new angular speed ofthe platform.

Suppose the platform with the kid in the previous problemis rotting in anticlockwise directioin at an angular speed omega . The kid starts walking along the rim with a speed v relative to the platform also in the anticlockwise direction. Find the new angular speed of the platform.

In the previous problem, initially the insect is at the edge and the disc is rotating with angular speed omega_(0) in clockwise direction. Now the insect starts walking along the rim with speed v relative to the disc also in clockwise direction. Find new angular speed of platfrom.

A circular platform is free to rotate in a horizontal plane about a vertical axis passing through its centre. A tortoise is sitting at the edge of the platform Now, the platform is given an angular velocity omega_(0) . When the tortoise moves along a chord of the platform with a constant velocity (with respect to the platform), the angular velocity of the platform will vary with time t as -

A boy of mass m is standing on a platform of M kept on smooth floor. If the body starts moving on the platform with a speed v_(0) relative to the platform , with what velocity to the floor does the platform recoil ?

A circular plarform is free to rotate in a horizontal plane about a vertical axis passing through its centre. A tortoise is sitting at the edge of the platform. Now, the platform is given an angular velocity omega_0 . When the tortoise move along a chord of the platform with a constant velocity (with respect to the platform), the angular velocity of the platform omega(t) will vary with time t as
