Question

A car of mass 1000 kg moves on a circular track of radius 20 m , if the coefficient of friction is 0.64 , what is the maximum velocity with which the car can be moved ?

Answer 1

Sorry can't understand the question I think so some grammatical mistake is there ok verify it and again edit the question

Answer 2

Answer :

The maximum velocity with which the car can be moved is 11.2 m/s

Step-by-step explanation:

Mass = 1000 kg

radius = 20 m

Coefficient of friction = 0.64

Since we know,

μmg = $\frac{mv^{2} }{r}$

where,

μ is the coefficient of friction

m is the mass

g is gravity with value 9.8 m / s²

v is the velocity

r is the radius

From the formula,

μmg = $\frac{mv^{2} }{r}$

μmgr = mv²

Dividing both sides by m,

μrg = v²

v = √μrg

Substituting the values,

v =  $\sqrt{0.64 * 20 * 9.8}$

v =  $\sqrt{125.44}$

v = 11.2 m /s

Hence,

The maximum velocity with which the car can be moved is 11.2 m/s
