When an old lp turntable was revolving at 33.3 rpm, it was shut off and uniformly slowed down and stopped in 5.5 seconds. through how many rotation did it turn while stopping?

No of revolution is defined as the no of loops taken from the starting to the end from the starting point . The number of rotations did it turn while stop will be 1.52.

No of revolution is defined as the no of loops taken from the starting to the end from the starting point.

The given data in the problem is;

n is the rpm of the old Ip =33.3 rpm

t is time interval taken to stop= 5.5 sec

N is the number of rotations did it turn while stopping=?

The angular speed is found by the formula as;

The rate of change of angular velocity is known as the angular acceleration;

The equation for the newtons law is given as

For one rotation the number of revolutions is n then for the N no of revolutions;

Hence the number of rotations did it turn while stop will be 1.52.
