14. A motorcycle accelerates at a rate of 4.21 m/s2
If the cyclist went from 8.2 m/s to 55.9 m/s,
how long did he accelerate?

Respuesta :

MathPhys

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

4.21 m/s² = (55.9 m/s − 8.2 m/s) / Δt

Δt = 11.3 s

Round as needed.
