As the car goes through the valley in part A the car's speed is 15 m/s, its mass is 20 kg and the radius of valley (r) is 5 meters, determine the magnitude of the centripetal force acting on the car. *

Respuesta :

Answer:

Centripetal force, F = 900 N

Explanation:

We have,

Speed of a car is 15 m/s

Mass of the car is 20 kg

Radius of the valley is 5 m

It is required to find the magnitude of the centripetal force acting on the car. The centripetal force acting on the car is due to the motion in circular path. The centripetal force is given by :

[tex]F=\dfrac{mv^2}{r}\\\\F=\dfrac{20\times (15)^2}{5}\\\\F=900\ N[/tex]

So, the centripetal force of 900 N is acting on the car.
