Question
While shopping in a mall, Abdullah helped his mother by pushing a trolley of
mass 32kg at a constant speed, for 12m by applying a constant horizontal
force of magnitude Fo on the trolley. If he did 420 J of work for this, determine
the value of Fo ? Now if he applies a force greater than Fo, how you will
describe the subsequent motion of the trolley.
300 N
Free-body diagrams for a situation is shown. If the body experiences a net
80 N

equal and opposite pairs and are therefore balanced. Thus, since there can never be such a thing as
an unbalanced force, how can any object ever accelerate?" Explain the mistake in this statement.
