Question

A bullet with a mass of 14.5 is shot out of a rifle that has a length 1.08. The bullet spends 0.14 on the barreL. What is the acceleration as it travels through the barrel

Answer 1

Answer:

110 m/s²

Explanation:

Given:

v₀ = 0 m/s

Δx = 1.08 m

t = 0.14 s

Find: a

Δx = v₀ t + ½ at²

1.08 m = (0 m/s) (0.14 s) + ½ a (0.14 s)²

a = 110 m/s²
