Acar with a mass of 1,500 kilograms is moving around a circular curve at a uniform velocity of 16 m/s. the curve has a radius of 100 meters. what's the centripetal force on the car?

Centripetal force can be computed using this formula.



where:
f= centripetal force
m = mass
v = velocity
r = radius

Everything you need is already and all you have to do is input it into your formula:
m = 1,500 kg
v = 16m/s
r = 100  m




or

The centripetal force in a circular motion is given by:

where m is the mass of the object, v its speed and r the radius of the circular path.
Using the data of this problem, m=1500 kg, v=16 m/s and r=100 m, and replacing them inside the formula, we find the value of the centripetal force:
