Question

A gymnast on a high bar swings two revolution in a time of 1.5 s. The direction of displacement is shown in the sketch below. Find the angular velocity in (rad/s) of the gymnast. . A clock uses a pendulum to keep time. Determine the length of a simple pendulum that will swing back and forth in simple harmonic motion with a period of 1.00 s. 2. A ceiling fan is turned on and a net torque of 1.9 N-m is applied to the blades. The blades have a total moment of inertia of 0.25 Kg.m2 What is the angular acceleration of the blades? 3.

Explanation / Answer

angular acceleration = torque / moment of inertia

= 1.9 / 0.25 = 7.6 rad / s^2 = or 7.6 N / Kg.m

pls rate thumbs up. plsssssssss
