A toy car is traveling down a small ramp. While it is at a height of 0.4 m, it is traveling down the ramp at 2.2 m/s (ignore friction and air resistance, and assume that the bottom of the ramp has a height of 0 m). What is the speed of the car when it reaches the bottom of the ramp? (Correct about 3.5 m/s.)
