Question

A water rocket can reach a speed of 76 m/s in 0.060 seconds from launch.

What is its average acceleration?

Answer 1

1300 m/s²

Step-by-step 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.
