A car is traveling in a race. The car went from the initial velocity of 35 m/s to the final velocity of 65 m/s in 5 seconds. What

is the acceleration?

-13 m/s

-6 m/s²

6mis?

13 m/s2

Acceleration = (change in speed) / (time for the change)

Change in speed = (speed after the change) - (speed before the change)

Change in speed = (65 m/s) - (35 m/s) = 30 m/s

Acceleration = (30 m/s) / (5 s)

Acceleration = 6 m/s²
