Q. A ball rolls horizontally off the edge of a tabletop that is 0.78 m high. It strikes the floor 2.80 m away from the edge of the table. What is the initial (horizontal) velocity of the ball?

Q. Suppose a car is traveling at 13.0 m/s, and the driver sees a traffic light turn red. After 0.540 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 6.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
