Bob is pushing a box across the floor at a constant speed of 1.5 m/s, applying a horizontal force whose magnitude is 75 N. Alice is pushing an identical box across the floor at a constant speed of 3 m/s, applying a horizontal force.

(a) What is the magnitude of the force that Alice is applying to the box?
