A driver is driving uphill. He maintained his throttle, causing his car to constantly decelerate as it is coming up the hill. The road going up the hill is 217 m long and it took him 8.8 seconds to get to the top of the hill. His speed has reduced to 22 m/s at that point. What was the car's acceleration (include a negative sign in your answer)? Hint: the initial position of the car can be set at the origin.

A driver is driving uphill. He maintained his throttle, causing his car to constantly
decelerate as it is coming up the hill. The road going up the hill is 217 m long and it
took him 8.8 seconds to get to the top of the hill. His speed has reduced to 22 m/s at
that point. What was the car's acceleration (include a negative sign in your answer)?
