[SOLVED] A roller coaster car rapidly picks up speed as it rolls down a hlope. 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.
