Question

CENTRIPETAL FORCE
A 1000-kg car rounds a turn of radius 30m at a velocity of 9m/s. How much centripetal force is required?

Answer 1

Answer:

centripetal force=mv^2/r

=>f=1000*81/30=270

Answer 2

The Centripetal Force Required Is 2,700 Newton.

GIVEN

Weight of the car = 1000kg

The radius of the curve = 30 meter

The velocity of the car = 9m/s

TO FIND:

Centripetal force.

SOLUTION:

We can simply solve the above problem as follows,

Centripetal force is defined as a force acting on the body undergoing a circular motion directed towards the centre of the circle around which the body is moving.

The formula to calculate centripetal force is-

$F(c) \: = \frac{m {v}^{2} }{r}$

where,

m = mass of the object

v = velocity

r = radius

putting the values in the above formula,

$F(c) = \frac{1000 \times 9 \times 9}{30}$

$F(c) = 2700 N$

Hence, the centripetal force required is 2,700 Newton.
