Determine the centripetal force upon a 40-kg child who makes 10 revolution around the cliffhanger in 29.3 seconds. the radius of the barrel is 2.90 meters

The centripetal force acting on the child is 39400.56 N.

Explanation:

Given:

Mass of the child is,

Radius of the barrel is,

Number of revolutions are,

Time taken for 10 revolutions is,

Therefore, the time period of the child is given as:

Now, angular velocity is related to time period as:

Now, centripetal force acting on the child is given as:

Therefore, the centripetal force acting on the child is 39400.56 N.
