2. A spaceship descends vertically downwards towards Earth. Before the spaceship reaches the surface of Earth, its height y above the ground is given by y=at + t+y where a, 3, and y are constants. a) What units must the constants a, , and y have? b) Find the velocity and acceleration of the spaceship as functions of time. -80 m/s, and c) Initially at t = 0 the position, velocity, and acceleration of the spaceship are y = ay = 3 m/s. Determine the values of the constants a, , and y. d) Using the initial values given in part c), how long will it take for the spaceship to reach the ground and what are the velocity and acceleration when it does reach the ground? 1000 m, Vy 2.
