Question

A company has a fireworks launcher that can launch a projectile from the ground at a speed of 48.0 m/s. How high can this fireworks shoot?

Answer 1

\[H=v^2\sin^2\theta/2g\]

I get 117.43

Answer 2

According to the answer key, it is 115, but I got your answer to using a kinematics equation.

Answer 3

hmmm do you use 9.8 or 10 for gravity? Idk how much a difference that makes but just a thought

Answer 4

9.8

Answer 5

I used 9.8 also so maybe using 10 will affected it?

Answer 6

Actually, if you use 10 you get 115.2, but our teacher told us to use 9.8

Answer 7

I think that was the reason.

Answer 8

Thanks!

Answer 9
