Question

On a circular racetrack with a radius of 3.23 m, a certain road car set a speed record of 3.72

m/s. If the car had a mass of 250 kg, what was the net force acting on it?

Answer 1

F = 1071.08 N

Step-by-step explanation:

Given that,

The radius of the circular track, r = 3.23 m

Speed of the car, v = 3.72 m/s

The mass of the car, m = 250 kg

We need to find the net force acting on it. The centripetal force will act on it and it is given by the relation as follows :

`F=(mv^2)/(r)\\\\F=(250* (3.72)^2)/(3.23)\\\\F=1071.08\ N`

So, the net force acting on the car is 1071.08 N.
