Question

A circular platform of radius Rp = 4.45 m and mass Mp = 423 kg rotates on frictionless air bearings about its vertical axis at 7.99 rpm. An 83.7-kg man standing at the very center of the platform starts walking (at t = 0) radially outward at a speed of 0.747 m/s with respect to the platform. Approximating the man by a vertical cylinder of radius Rm = 0.245 m, determine an equation (specific expression) for the angular velocity of the platform as a function of time. What is the angular velocity when the man reaches the edge of the platform?

Explanation / Answer

By reciprocating the radius of all moving speeds you'll be able to form a conclusive effect known as the Pendulum Theory. Therefore your answer would be e=mc2
