Question

A drag racer starts her car from rest and

accelerates at 6.2 m/s for the entire distance
of 367 m.
How long did it take the car to travel this
distance?
Answer in units of s.

Answer 1

10.9 s

Step-by-step explanation:

Given:

Δx = 367 m

v₀ = 0 m/s

a = 6.2 m/s²

Find: t

Δx = v₀ t + ½ at²

367 m = (0 m/s) t + ½ (6.2 m/s²) t²

t ≈ 10.9 s
