3. A fighter jet lands on the flight deck of an aircraft carrier. The jet must reduce its speed from about 153 m/s to exactly 0 m/s in 2.0 s or it will fall off the back of the carrier into the ocean. What is the jet's acceleration? 4. Arunner whose initial speed is 2.9 m/s increases her speed to 3.1 m/s in order to win the race. If the runner takes 5.0 s to complete this increase in speed, what is her acceleration? 5. A certain roller coaster accelerates its cars 6.35 m/s? up the first incline. If this acceleration happens during the first 7.0 s of the ride, how much does the coaster's speed increase? 6. A solid-fuel rocket boosters used to launch a space shuttle above the Earth's surface. During that time, the shuttle undergoes a total acceleration of 6.25 m/s?, so that its speed increases from rest to about 750 m/s. How long does it take for the shuttle to reach this speed? 7. In 1995, Bonnie Blair set the world record for speed skating. Suppose that she coasted to a stop on the ice after she crossed the finish line. If hér initial speed was 13 m/s, and her acceleration was -2.9 m/s, how long did it take her to stop?
