During a physics experiment, a trolley is released from rest at the top of a ramp. It accelerates uniformly down the ramp. The length of the ramp is 4.5 m4.5\text{ m}4.5 m, and the trolley reaches a final speed of 6.0 m/s6.0\text{ m/s}6.0 m/s at the bottom of the ramp. Calculate the acceleration of the trolley.
