Answer :

The acceleration of the edge of rotor will be 5707 rad/s^2

It is given that

r = 7.165 cm = 0.07165 m

Angular speed, w = 2695.0 rpm

2695 X 2π/60

282.2197 rad/sec

Acceleration is the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

The acceleration will be

a = w²r

a = 282.2197^2 x 0.07165

a = 5706.77 rad/sec²

Hence, acceleration of the edge of rotor will be 5707 rad/s^2
