Question

(e) A car of mass 1000 kg is travelling up a 50 gradient at initial speed 10 m s-1, with the engine off. The brakes are applied at this time and the car travels distance s along the road before stopping. Friction in the brakes causes an increase in internal energy of 3 x 104 J. No energy transfer to or from the car occurs. Find distance s.How can I solve this step by step?

    A 2000 kg truck is moving with speed 20 m/s. A 1000 kg car is moving with speed 40 m/s. Both apply the brakes, which exert the same constant braking force, and are brought to rest. Which vehicle travels the greatest distance before stopping? I'm looking for a worked out example, thanks!

    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...

    5. A runaway truck with a mass of 2100 kg strikes a car of mass 1350 kg, which was at rest before the collision. The car’s wheels are locked during the entire event, but the truck has no brakes, i.e., it is rolling freely on the road. The two vehicles move forward together, and the car’s tires leave skid marks for a distance of 1.5 m. Suppose that the coefficient of kinetic friction between the car’s tires and the road...

    The car shown has a mass of m=1000 kg and a center of mass located at G. The coefficient of static friction between the wheels and the road is μs=0.250. The dimensions are a=1.15 m, b=1.55 m, and c=0.290 m. Assume the car starts from rest, the wheels do not slip on the road, and that the car experiences constant acceleration. Neglect the mass of the wheels. Part A - Shortest Time to Reach a Given Speed with Rear-Wheel Drive...
