What is the maximum speed with which a 1200-kg car can round a turn of radus 84.0 m on a flat road if the coefficient of static friction between tires and road is 0.60. express your answer to two significant figures and include the apprepriate units.

Explanation:

It is given that,

Mass of the car, m = 1200 kg

Radius of circular path, r = 84 m

The coefficient of static friction between tires and road is 0.60

Static friction is given by :

..............(1)

When an object is moving in a circular path, the centripetal force will act on it. It is given by :

Let v is the maximum speed of the car. From equation (1) and (2) as :

g = acceleration due to gravity

v = 22.22 m/s

or

v = 22 m/s

Hence, this is the required solution.

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
