7. Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/S2 until it reaches a speed of 80 ft/s. Afterwards it maintains this speed. Also, when to, car B located 6000 ft down the road is traveling towards A at a constant speed of 60 ft/s. Determine the distance traveled by car A when they pass each other.
8. A ball is thrown with an upward velocity of 5 m/s from the top of a 10-m high building. One second later another ball is thrown vertically from the ground with a velocity of 10 m/s. Determine the height from the ground where the two balls pass each other.
