A car enters a 300-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the road is 0.300. What is the maximum speed at which the car can travel around this curve without sliding?

The maximum speed at which the car can travel around this curve without sliding is 29.69

Explanation:

Given:

Coefficient of static friction

Radius of curve m

Here in our question car move in circular path so force is given by,

From the formula of centripetal force,

Where Normal force

Where

Therefore, the maximum speed at which the car can travel around this curve without sliding is 29.69

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
