Question

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

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

Answer:

Force, F = 135 N

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 :

$F=ma$

$F=90\ kg\times 1.5\ m/s^2$

F = 135 N

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