Question

car moving along a straight section of road starts from rest, accelerating at 2.00 m/s? until it reaches a speed of 25.0 m/s. Then the vehicle moves for 87.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s (a) How long is the three-wheeled car in motion (in s)? (b) What is the average velocity of the three-wheeled car for the motion described? (Enter the magnitude in m/s.) m/s

    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...
