The blade of a windshield wiper moves through an angle of 180.0 degrees in 0.500 s. The tip of the blade moves on the arc of a circle of radius of 0.520 m. What is the magnitude of the centripetal acceleration of the tip of the blade

Centripetal acceleration will be equal to

Explanation:

We have given time taken to cover 180° is 0.5 sec

So time taken by 360° is equal to = 2×0.5 = 1 sec

Radius of the circle r = 0.520 m

So distance

So velocity

We have to find the centripetal acceleration

Centripetal acceleration will be equal to

So centripetal acceleration will be equal to
