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?

Respuesta :

Mass = 900kg,  Acceleration = 2.1 m/s²

Force = ma

Force = 900 * 2.1 = 1890 N

Answer:

The centripetal force acting on the car is 1890 N.

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

[tex]F_{c}=m\dfrac{v^2}{r}[/tex]

F = centripetal force

[tex]\dfrac{v^2}{r}[/tex] = centripetal acceleration

Put the value into the formula

[tex]F_{ac}=900\times2.1[/tex]

[tex]F_{ac}=1890\ N[/tex]

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