I have three questions I need assistance on please: 1. To make an object start moving on a surface with friction requires (a) less force than it takes to keep it moving on the surface at constant velocity (b) the same force as to keep it moving on the surface at constant velocity (c) more force than it takes to keep it moving on the surface at constant velocity (d) a force equal to the weight of the object (2)...

6. A 50.0 kg man standing on a spring scale takes a descending elevator ride (DOWNWARD). Starting from the rest, the elevator descends, attaining a maximum speed of 6.0 m/s in 2.0 seconds. Then the elevator travels with this constant speed of 6.0 m/s for 10.0 seconds. Lastly, it takes the elevator 3.0 second to make a complete stop. Based on the information above, answer the...

There are (one can say) three coequal theories of motion for a single particle: Newton's second law, stating that the total force on an object causes its acceleration; the work-kinetic energy theorem, stating that the total work on an object causes its change in kinetic energy; and the impulse-momentum theorem, stating that the total impulse on an object causes its change in momentum. In this problem,...
