A 1300-kg car, initially at rest, is initially accelerated at 4.9m/s2. After the car moves 550m, the engine is cut off. The car then moves a distance of 1230 before coming to a stop. Assume the road to be level and that g = 10 N/kg. a) What is in m/s, the magnitude of the velocity of the car at the end of the first 550m? b) What is in m/s2, the magnitude of the acceleration of the car while...

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...

The brakes are applied to a moving van, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.90 s to a final velocity of 2.00 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? m/s (b) What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction...
