A child of mass 47 kg sits on the edge of a merry-go-round with radius 1.3 m and moment of inertia 56.3953 kg m2 . The merrygo-round rotates with an angular velocity of 1.6 rad/s. What radial force does the child have to exert to stay on the merry-go-round?

the child have to exert this much amount of force radially to stay on the wheel.

Explanation:

Given:

mass of the child,

radius of the merry-go round wheel,

moment of inertia of the wheel,

angular velocity of the wheel,

Since the child is sitting on the edge of the rotating wheel the child will feel and outward throwing force called centrifugal force.

Centrifugal force is mathematically given as:

the child have to exert this much amount of force radially to stay on the wheel.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
