A tortoise is sitting at the edge of the platform. Now the platform is given an angular velocity ω0 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 ω(t) will vary with time t as

an angular acceleration of 25 rad/s^2 must be applied about that axis for a duration of The moment of inertia of a body about a given axis is 1.2 kg m^2. Initially the body is at rest. In order to produce a rotational kinetic energy of 1500 J
