Suppose the coefficient of static friction between the road and the tires on a car is 0.586 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 36.0 m radius?

14.38 m/s

Explanation:

We are given that

The coefficient of static friction between the road and the tires on a car=

Radius of curve=r=36 m

We have to find the speed will put the car on the verge of sliding as it rounds a level curve.

Magnitude of acceleration of car=

By Newton's second law

Where =Friction force

If car does not slip then

The maximum speed with which the car can round the curve without slipping

Substitute the values and taking g=

Hence, the speed of the car on the verge of sliding as it round a level curve=14.38 m/s

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
