Question

A boy with a mass of 30kg rides a merry-go round with a radius of 1.5 meters and a velocity of 0.38 m/s. What is the centripetal force on the boy? __N

Answer 1

Answer:

The centripetal force on the boy = 2.888 N

Explanation:

Given:

m = 30 kg

r = 1.5 m

v = 0.38 m/s

To Find:

The centripetal force on the boy = ?

Solution:

F = m x v^2 / r

F = 30 kg x (0.38 m/s)^2 / 1.5 m

F = 30 x 0.1444 / 1.5

F = 2.888 N

Therefore,

The centripetal force on the boy = 2.888 N
