Question

A ball of mass 0.2 kg is tied to a string and whirled in a horizontal circle of radius 0.4 m. If the ball makes 10 complete revolutions in 4 seconds, determine the linear speed centripetal acceleration and centripetal force.

Answer 1

Answer:

When a ball connected with a string is whirled in a horizontal circle of radius R, then the ball will feel a Pseudo force away from the center of the circle called the centrifugal force which is exactly equal to the centripetal force on the ball due to the circular motion.
