A car pulls away from an intersection when the light turns green. After uniformly accelerating for the next 6.0 s, the car has traveled a distance of 75 m. The car then proceeds at a constant speed. ( /7) (a) What was the car's acceleration?
(b) How fast was the car traveling when it finished accelerating?
(c) How long will it take for the car to travel another 85 m at this constant speed?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
