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?

In 10 seconds a car accelerates 4/ms to 60m/s. how fast was the car going before it accelerated?
