Question

A car of mass 900 kg drives around a circle with a centripetal acceleration of 2.1 m/s2. What is the centripetal force acting on the car?

Answer 1

Mass = 900kg, Acceleration = 2.1 m/s²

Force = ma

Force = 900 * 2.1 = 1890 N

Answer 2

The centripetal force acting on the car is 1890 N.

Step-by-step explanation:

Given that,

Mass of car = 900 kg

Centripetal acceleration = 2.1 m/s²

We need to calculate the centripetal force

Using formula of centripetal force

`F_(c)=m(v^2)/(r)`

F = centripetal force

`(v^2)/(r)` = centripetal acceleration

Put the value into the formula

`F_(ac)=900*2.1`

`F_(ac)=1890\ N`

Hence, The centripetal force acting on the car is 1890 N.
