Awater rocket can reach a speed of 76 m/s in 0.060 seconds from launch.
what is its average acceleration?

1300 m/s²

Explanation:

Average acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (76 m/s − 0 m/s) / 0.060 s

a = 1266.67 m/s²

Rounded to two significant figures, a ≈ 1300 m/s².

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
