Question

If the force of a 10 kg car traveling in a circular path is 900n and the circle has a diameter of 20 m what is the velocity of the car

Answer 1

the velocity of the car is 30 m/s.

Step-by-step explanation:

Given;

Centripetal force on the car, F = 900 N

mass of the car, m = 10 kg

diameter of the circular path, d = 20 m

radius of the circular path, r = 10 m

The velocity of the car is calculated as follows;

`F = (mv^2)/(r) \\\\mv^2 = Fr\\\\v^2 = (Fr)/(m) \\\\v = \sqrt{(900 * 10)/(10) } \\\\v = 30 \ m/s`

Therefore, the velocity of the car is 30 m/s.
