Calculate the maximum acceleration of a car that is heading up a 6∘ slope (one that makes an angle of 6∘ with the horizontal) under the following road conditions. Assume that only half the weight of the car is supported by the two drive wheels and that the coefficient of static friction is involvedthat is, the tires are not allowed to slip during the acceleration. (Ignore rolling).
a) On dry concrete:
b) On wet concrete:
c) On ice, assuming that the coefficient of static friction is the same as for shoes on ice:
Hint: For each of (a), (b), and (c), you will need to determine the appropriate coefficient of static friction. What forces (or components thereof) act on the car? How is the normal force affected, given that the drive wheels only support half of the car's weight?

Calculate the maximum acceleration (in m/s2) of a car that is heading down a 6.290 slope (one that makes an angle of 6.290 with the horizontal) under the following road conditions. You may assume that the weight of the car is evenly distributed on all four tires and that the static coefficient of friction is involved-that is, the tires are not allowed to slip during the acceleration. (Ignore rolling friction. Assume the positive direction is down the slope. Indicate the...

You are driving your car along a flat, curved road; the curve in the road is a segment of a circle with radius 50 meters. (We call this a "radius of curvature"). How fast can the car drive around the curve if the coefficient of static friction between the tires and the road is 1.0 (tires on dry pavement)? What if the coefficient of friction is 0.2 (tires on ice)?
