Question

A child rides a bicycle in a circular path withí a radius of 3.0 m. The

tangential speed of the bicycle is 2.0 m/s. The combined mass of the bicycle and the child is 43 kg.

Answer 1

57.3N

Step-by-step explanation:

Given parameters:

radius of the path = 3m

tangential speed = 2m/s

mass of the bicycle and child = 43kg

Unknown:

centripetal force = ?

Solution:

The centripetal force is the inward force on a body round a circular path.

It is expressed as;

F =
`(mv^(2) )/(r)`

F is the centripetal force

m is the mass

v is the tangential speed

r is the radius

F =
`(43 x 2^(2) )/(3)` = 57.3N
