Question

a car of mass 1500 kg rounds a curve of radius 250 m at 90 km/hour calculate the centripetal force acting on it​

Answer 1

Mainly there are two types of Forces that acts while a body is moving in circular path.

1. Centripetal Force :-

A force that acts on the body which is moving in circle and is directed towards the centre around which body is moving.

2. Centrifugal Force

Here, this force is totally opposite of Centripetal Force. It is a force that acts on the body which is moving in circle and is directed away from the centre around which body is moving.

Now, Coming to Question.

Given :-

Mass of the body = m = 1500 Kg

Radius of circular path = r = 250 m

Velocity of body = v = 90 Km/h = 25 ms-¹

As we know that,

F = mv²/r

F = (1500 × 25 × 25)/250

F = 3750 N

Hence,

Centripetal Force = F = 3750 N.
