A worker pushing a 35.0 - kg wooden crate at a constant

speed for 12.0 m along a wood floor does 350 J of work by

applying a constant horizontal force of magnitude F_{0} on the

crate. (a) Determine the value of F_{0}. (b) If the worker now

applies a force greater than F_{0}, describe the subsequent

motion of the crate. (c) Describe what would happen to the

crate if the applied force is less than F_{0}.

Step 1

a)

Write the expression for force applied by the person,

Step 2

b)

From part (a) the horizontal force F0 is 29.2N

When the applied force is greater than the horizontal force F0 which is 29.2N the wooden crate moved in direction of the applied force, as a result the speed of the w...
