1. A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its

speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its
average acceleration?

Answer:

6 m/s²

Step-by-step explanation:

Average acceleration = change in velocity / change in time

a = Δv / Δt

a = (22 m/s − 4 m/s) / 3 s

a = 6 m/s²
