Question

5. In Figure 4.7, the net external
force on the 24-kg mower is stated
to be 51 N. If the force of friction
Fnet
opposing the motion is 24 N, what
force F (in newtons) is the person
exerting on the mower? Suppose
the mower is moving at 1.5 m/s
when the force F is removed.
How far will the mower go before stopping?

Two forces are applied to a 4.0 kg cart on a rough surface as shown. At a certain instant, force A is 32 N to the right, and force B is 20 N to the left. The friction force is 2.0 N. What is the acceleration of the cart at this instant, in m/s?? (Hint: What is the direction of the friction in this case? Draw a free-body diagram.) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
