A 150. kg bobsled is being pushed on a flat surface by its team members with a constant force of 450. N [S]. The coefficient of kinetic friction between the bobsled and the ice track is 0.010. The push lasts for 4.0 s and then the bobsled is allowed to slide on its own until it comes to rest. Hint free body diagrams in your rough work will help you solve. a. Determine the force of friction on the box(include direction)

b. Determine the acceleration of the box as it is being pushed (include direction).

c. Calculate the speed of the box just as the push stops.

d. Determine the acceleration of the box as it is sliding on its own (with the force no longer applied). Include direction

e. What total distance did the box travel (including the time the force was applied and the time the force was removed) ?
