Question

You push a 22.0 kg box along a rough floor at a constant velocity. The coefficient of kinetic friction between the box and the floor is 0.45. You then release the box and it slows to a stop.
a) For the time where you are pushing the box, draw a free body diagram of the box and calculate the value of each force as you can on your free body diagram.

b) For the time where you have released the box, draw an FBD of the box. Determine the value of the forces on the FBD and determine the unbalanced force.

c) What will the acceleration of the box be when it is released and slowing to a stop?

Answer 1

The answer is actually 22.0
