6. A dog sees a flowerpot sail up and then back down past a window which is 1.47m high. If the total time the pot is in sight is 1.0 s, find the hcight above the window the pot rises. 7. Suppose the first one-fourth of the distance between two points is covered with an average velocity of +18 m/s. The average velocity for the remainder of the trip is +51 m/s. What is the average velocity for the entire trip? 8. A train has a length of 92 m and starts from rest with a constant acceleration at t = 0. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At t 14 s, the car reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at a time t 28 s, the car is again at the rear of the train. Find the magnitude of (a) the car's velocity and (b) the train's acceleration.
