Question

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 telescope
upward 50.0 degrees to see the rocket. What was the average speed of the rocket?
Hint: For average speed, use this equation for average velocity: (vavg) =td d2 1 -
,
where d2 and d1 are the final and starting distances (so d2 – d1 is the distance traveled)
and t is the time it took to travel that distance.
Use a problem-solving strategy to solve this on

Answer 1

First hint :)
