**88. A football player, starting from rest at the line of scrimmage, ac- celerates along a straight line for a time of 1.5 s. Then, during a neg- ligible amount of time, he changes the magnitude of his acceleration to a value of 1.1 m/s². With this acceleration, he continues in the same direction for another 1.2 s, until he reaches a speed of 3.4 m/s. What is the value of his acceleration (assumed to be constant) during the initial 1.5-s period?

1. In 1992, a 14-kg meteorite struck a car in Peekskill, NY, leaving a 20-cm-deep dent in the trunk. If the meteorite was moving at 500 m/s before striking the car, what was the magnitude of its acceleration while stopping?
A student at the top of a building of height h throws one ball upward with a speed of i and then throws a second ball downward with the same initial speed i. Just before it reaches the ground, is the final speed of the ball thrown upward (a) larger, (b) smaller, or (c) the same in magnitude, compared with the final speed of the ball thrown downward?
A hard rubber ball, not affected by air resistance in its motion, is tossed upward from shoulder height, falls to the sidewalk, rebounds to a smaller maximum height, and is caught on its way down again. This motion is represented in Figure OQ2.13, where the successive positions of the ball through are not equally spaced in time. At point the center of the ball is at its lowest point in the motion. The motion of the ball is along a straight, vertical line, but the diagram shows successive positions offset to the right to avoid overlapping. Choose the positive y direction to be upward. (a) Rank the situations through according to the speed of the ball |vy| at each point, with the largest speed first. (b) Rank the same situations according to the acceleration ay of the ball at each point. (In both rankings, remember that zero is greater than a negative value. If two values are equal, show that they are equal in your ranking.) Figure OQ2.13

We’ve seen that a man’s higher initial acceleration means that he can outrun a horse in very short race. A simple—but plausible—model for a sprint by a man and a horse uses these assumptions: The man accelerates at 6.0 m/s2 for 1.8 s and then runs at a constant speed. A horse accelerates at 5.0 m/s2 but continues accelerating for 4.8 s and then continues at a constant speed. A man and a horse are competing in a 200 m race. The man is given a 100 m head start, so he begins 100 m from the finish line. How much time does the man take to complete the race? How much time does the horse take? Who wins the race?
1.A sprinter starting from rest on a straight, level track is able to achieve a speed of 12 m/s in 6.0 s. What is the sprinter’s average acceleration? 2.Modern oil tankers weigh more than a half-million tons and have lengths of up to one-fourth mile. Such massive ships require a distance of 5.0 km (about 3.0 mi) and a time of 20 min to come to a stop from a top speed of 30 km/h. What is the magnitude of such a ship’s average acceleration in m/s2 in coming to a stop? 3.A motorboat starting from rest travels in a straight line on a lake. (a) If the boat achieves a speed of 8.0 m/s in 10 s, what is the boat’s average acceleration? (b) Then, in 5.0 more seconds, the boat’s speed is 12 m/s. What is the boat’s average acceleration for the total time?

As an observant physicist, you make measurement of this cat's motion and construct a graph of the feline's velocity as a function of time. What distance (in cm) does the cat move from t=0 to t=7.5s?

In 2008, at the Beijing Olympics, Usain Bolt of Jamaica reclaimed his title as the world's fastest man. He completed the l00m final in a world record time of 9.69 s. He accelerated uniformly from rest for the first 6.5 seconds, covering 60 m before coasting at maximum speed to the finish. Calculate his average speed for the first 6.5 s.
