Part A:

A car is parked on a steep hill. The following forces act on thecar:

- the Earth's gravitational pull
- normal reaction of the pavement
- static friction of the pavement
- the car's weight

Part B:
A golf ball is flying through the air. The following forces act onthe ball:

- the Earth's gravitational pull
- air drag
- the force of your hand
- inertia

For part B, I think 1,2,3 are correct. Is this right? I'm not surewhat the answer is to Part A.

If the coefficient of static friction between tires and pavement is 0.8, calculate the minimum torque that must be applied to the 67-cm-diameter tire of a 935-kg automobile in order to "lay rubber" (make the sheels spin, slipping as the car accelerates). Assume each wheel [is a disk that] supports an equal share of the weight.

A curve of radius 139 m is banked at an angle of 9°. An 758-kg carnegotiates the curve at 77 km/h without skidding. Neglect theeffects of air drag and rolling friction. Find the following.

(a) the normal force exerted by the pavement on the tires

(b) the frictional force exerted by the pavement on the tires

(c) the minimum coefficient of static friction between the pavementand the tires
