Jermaine runs exactly 2 laps around a 400 meter track. At the beginning of her run the clock read 3:02:00 PM. At the end her clock read 3:04:45 PM. Find the distance (d) the person traveled. calculate the speed using distance and total time. find the displacement. calculate the velocity. HELP

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.
