Question

A bicyclist of mass 90 kg drives around a circle with a centripetal acceleration

of 1.5 m/s2. What is the centripetal force acting on the bicyclist?

Answer 1

given,

mass of bicyclist(m)=90Kg

centripetal acceleration(a)=1.5 m/s2

centripetal force(F)=ma= 90×1.5=145 N

Answer 2

Force, F = 135 N

Step-by-step explanation:

Given that,

Mass of the bicyclist, m = 90 kg

Centripetal acceleration of the bicyclist,
`a=1.5\ m/s^2`

To find,

The centripetal force acting on the bicyclist.

Solution,

When an object moves in a circular track, it will under the action of centripetal acceleration and the exerted force is called centripetal force. It can be calculated as :

`F=ma`

`F=90\ kg* 1.5\ m/s^2`

F = 135 N

So, the centripetal force acting on the bicyclist is 135 N.
