3. a. A projectile of mass M is ejected from a launcher making an angle with the vertical.
Suppose the projectile is propelled by a time dependent force F(t) KeVe for a short period of T
(K and c are known constants). What is the velocity and the position of the projectile at To?
b. Assuming air resistance is negligible, what is the final position roxy) of the projectile at its
maximum height? Note that the projectile will be in a free-fall mode after To
