Question

A rabid 3kg racoon accelerates uniformly from rest to a speed of 14m/s in 0.45 seconds. Find the

average acceleration of the racoon.

Answer 1

Answer: 31.1 m/s²

Step-by-step explanation:

avg. accel. = (Vfinal - Vinitial) / Δt

Vfinal = 14 m/s

Vinitial = 0 m/s

Δt = 0.45 s

avg. accel. = (14 m/s - 0 m/s)/0.45 s = 31.1 m/s²
