Question

If a gun is fired straight up and has a muzzle velocity of 424 m/s how long will it take the bullet to reach its maximum height?

I need a lot of help.

Answer 1

43.3 s

Step-by-step explanation:

At the maximum height, the velocity is 0 m/s.

Given:

v₀ = 424 m/s

v = 0 m/s

a = -9.8 m/s²

Find: t

v = at + v₀

0 = -9.8t + 424

t ≈ 43.3

The time is approximately 43.3 seconds.
