Question

A 8.72 kg particle moves from the origin to position C , having coordinates x = 2.04 m and y = 2.04 m as shown in Figure 1. A particle moving in a horizontal plane from the origin to position C experiences a friction force with constant magnitude 2.32 N. Calculate the work that you must do to slide the particle at constant speed against the friction force as the particle moves along the diagonal path.

Answer 1

you must balance the friction by applying an equal and opposite force, or 2.32N
work = force * distance = 2.32*2.04√2
