Question

A car has an initial velocity of 2.4 m/s and accelerates at a constant acceleration to a velocity of 20 m/s over a time period of 20 s. Determine the car's displacement over the period.

Answer 1

Answer:

224 m

Explanation:

Given:

v₀ = 2.4 m/s

v = 20 m/s

t = 20 s

Find: Δx

Δx = ½ (v + v₀) t

Δx = ½ (20 m/s + 2.4 m/s) (20 s)

Δx = 224 m
