Acceleration worksheet

Question

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 1

Average acceleration is the final velocity minus the initial velocity divided by the time interval.

acc = 22 m/s - 4 m/s / 3 s = 6 m/ s²
