In Mud buggy driving, people attempt to drive an off-road vehicle over a deep mud puddle. If the buggy stops before the end , it sinks into the mud and needs to be pulled out with a tow truck. A racer is driving his mud buggy in a straight line. when he hits the edge of the mud puddle, he is going 20 m/s. when he gets to the other side of the 25 m wide puddle he has slowed to 5m/s.

In Mud buggy driving, people attempt to drive an off-road vehicle over a deep mud puddle. If the buggy stops before the end , it sinks into the mud and needs to be pulled out with a tow truck. A racer is driving his mud buggy in a straight line. when he hits the edge of the mud puddle, he is going 20 m/s. when he gets to the other side of the 25 m wide puddle he has slowed to 5m/s. 
Assuming a constant acceleration, what was the mud buggy's acceleration while driving through the puddle and how long would it take to cross the puddle?
