A worker pushing a 35.0-kg wooden crate at a constant speed for 13.7 m along a wood floor does 390 J of work applying a constant horizontal force of magnitude F0 on the crate.Determine the value for F0.
Work is applied force times distance.
F0 * 13.7 m = 390 J
F0 = 28.5 N
The speed does not matter. Neither does the weight.
