A space shuttle is launched from rest. It takes 8.00 s to reach 158 km/h , and at the end of the first 1.00 min its speed is 1580 km/h .
Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the interval from 8.00 s to 1.00 min?
A stone is thrown from the top of a building and given an initial velocity of 17.0 m/s straight upward. The building is 25.0 m high, and the stone just misses the edge of the roof on its way down. Using t1 = 0 as the time the marble leaves the thrower’s hand, determine:
the time at which the stone reaches its maximum height, and
the velocity and position of the marble at t = 4.00 s.
A cheetah can accelerate from rest to 23.5 m/s in 2.00 s. Assume that the acceleration is constant over the time interval.
A runner can accelerate from rest to 7.90 m/s in the same time, 2.00 s. By what factor is the cheetah’s average acceleration magnitude greater than that of the runner?

- I am having trouble finding the average velocity of a truck in a problem. The problem states, "A truck on a straight road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 20.0 m/s. Then the truck travels for 60.0 s at constant speed until the brakes are applied, stopping the truck in a uniform manner in an additional 5.00 s." I know that the truck is in motion for 75 seconds and I know that average velocity is displacement/time but I havent been able to get the right number.arrow_forwardAn automobile traveling at 15.0 km/h along a straight, level road accelerates to 65.0 km/h in 6.00 s.
