Question

A car of mass 1000kg moves on a circular track of radius 20m. if the coefficient of friction is 0.64, then the maximum velocity with wch the car move is:

Answer 1

here is the answer to ur question

Answer 2

Answer:

v = 11.2 m/s

Explanation:

It is given that :

Mass of the car, m = 1000 kg

Radius of the track, r = 20 m

The coefficient of friction, $\mu=0.64$

We need to find the maximum velocity with which the car move. It can be calculate using balancing centripetal force and frictional force i.e.

$\dfrac{mv^2}{r}=\mu mg$

$v=\sqrt{\mu gr}$

$v=\sqrt{0.64\times 9.8\times 20}$

v = 11.2 m/s

So, the maximum velocity of the car is 11.2 m/s. Hence, this is th required solution.
