You are driving a 2500.0-kg car at a constant speed of 14.0 m/s along a wet, but straight, level road. as you approach an intersection, the traffic light turns red. you slam on the brakes. the car’s wheels lock, the tires begin skidding, and the car slides to a halt in a distance of 25.0 m. what is the coefficient of kinetic friction between your tires and the wet road?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
