Question

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 20m/s. When he gets to the other side of the 25m wide puddle he has slowed to 5m/s. Assuming constant acceleration what was the mud buggys acceleration while driving through the puddle and how long did it take to cross the puddle?

Answer 1

going across the puddle,

s = 20t - 1/2 at^2 = 25
v = 20 - at = 5

solve for a and t.
