73. ssm Only two forces act on an object (mass = 4.00 kg), as in the
drawing. Find the magnitude and direction (relative to the x axis) of the
acceleration of the object.

A woman exerts a constant horizontal force on a large box. As a result, the box moves across a horizontal floor at a constant speed "v0". The constant horizontal force applied by the woman:
has the same magnitude as the weight of the box.
is greater than the weight of the box.
has the same magnitude as the total force which resists the motion of the box.
is greater than the total force which resists the motion of the box.
is greater than either the weight of the box or the total force which resists its motion.
If the woman in the previous question doubles the constant horizontal force that she exerts on the box to push it on the same horizontal floor, the box then moves:
with a constant speed that is double the speed "v0" in the previous question.
with a constant speed that is greater than the speed "v0" in the previous question, but not necessarily twice as great.
for a while with a speed that is constant and greater than the speed "v0" in the previous question, then with a speed…
