Homework Statement
A crate is initially at rest on a rough, horizontal floor. The crate moves in a straight line as it is pushed resulting in the crate speeding up at a constant rate of 2.85 m/s2. After a while, the crate is no longer being pushed and the crate slows down at a constant rate of 4.17 m/s2. The crate comes to rest a total distance 92.7 m away from its starting position. For how long (amount of time) was the crate pushed?
