A 1300 kg car coasts on a horizontal road with a speed of 18 m/s. After crossing an unpaved, sandy stretch of road 38.5 m long its speed decreases to 14 m/s. (a) Was the net work done on the car positive, negative, or zero? positive zero negative Explain. This answer has not been graded yet. (b) Find the magnitude of the average net force on the car in the sandy section.

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...

A 72.5-kg skier coasts up a snow-covered hill that makes an angle of 22.9 ° with the horizontal. The initial speed of the skier is 8.71 m/s. After coasting a distance of 1.19 m up the slope, the speed of the skier is 3.74 m/s. (a) Find the work done by the kinetic frictional force that acts on the skis. (b) What is the magnitude of the kinetic frictional force?

An open train car, with a mass of 2030 kg, coasts along a horizontal track at the speed 2.33 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 3.41 s at the rate of 425 kg/s. What is the car\'s speed after the loading is completed? Ignore rolling friction (as unrealistic as that may be).
