# A cylinder rotati

Answer :

The time taken to attain equal angular speed is 25 sec

Given

The wheel rotates at a speed angular speed of 50 rev/s, at constant torque both acting in positive and negative acceleration.

Formula Used

The formula used is same as that of the formula for the relationship of velocity and acceleration in basic kinematics. where

The initial velocity of the motion is denoted by ω and the final velocity is denoted by ω0

Explanation

First let us find the angular velocity of the first cylinder  The time taken for the two cylinders to have equal velocity is   Rate this question :
