Question

A truck starts with a velocity of 50 m/s and uniformly accelerates to the right until it reaches a velocity of 155 m/s. If this change in velocity occurs over time of 3.9 seconds, what is the average acceleration of the race car

Answer 1

Step-by-step explanation:

Average acceleration is change in velocity over time.

a = Δv / Δt

a = (155 m/s − 50 m/s) / 3.9 s

a = 26.9 m/s²
