I am having so much trouble with this D:
A rocket is traveling straight up from its launch pad. An observer 5.00 km from the launch pad notices that at one instant, she must tilt her telescope 45.0 degrees upward to see the rocket. 10.0 seconds later, she must tilt her rocket upward 50.0 degrees to see the rocket. What was the average speed of the rocket?

(5.00 km)*(tan 50  tan 45)/(10.0 s)
= 0.096 km/s
