A projectile is launched vertically from a launch pad with an unknown initial velocity, V0. An unknown time, T, later, an observer is in a pickup which is traveling in such a way that the angle of elevation to the projectile is 22° and increasing at 2° per second. When the pickup is 750 m away from the launch pad, it is moving away from the launch pad at 25 m/sec. h(t) = -4.9t2 + V0 t , and that v(t) = h‘(t).
A) Find the initial velocity, V0.
B) Find the time, T, since launch.
