Problem

In bobsled, the team pushes the sled at the start to give it maximum speed before jumping in. Consider a simplified model: a

150\;\text{kg}

bobsled is pushed by two athletes who each apply a constant horizontal force of

400\;\text{N}

for

3.0\;\text{s}

before jumping aboard. During the push phase, the sled experiences a friction force of

120\;\text{N}

opposing its motion. The track is horizontal during this initial phase. What is the sled's speed when the athletes jump aboard?
