Pls help I’m literally going to fail this class A car accelerates at a rate of 10m/s2 for 15 seconds, drives up a ramp and jumps over a bus before landing and coming to a stop. Does the car ever count as a projectile during any of this motion. If so, at what point? If not, why not?

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.
