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 the car’s acceleration?

Acceleration = (change of speed) / (time for the change)
Change in speed = (22 - 4) = 18 m/s. Time for the change = 3 sec.
Acceleration = 18/3 = 6 m/s per second.

The acceleration of the roller coaster car is calculated by taking the change in speed and dividing it by the time taken. This results in an acceleration of 6 m/s². Therefore, as the car rolls down the slope, it speeds up at a rate of 6 meters per second every second.
