18.Which force would balance the two forces drawn from a point mass?d.
19. Calculate the resultant of two forces if one force is pointing in the positive x-direction with 100 N and the otherin the negative x-direction with 65 N?
20.Calculate the resultant force vector from two other vectors; the first one pointing 30oabove the positive x-axiswith magnitude 50 N and the second pointing in the negative y-direction with magnitude 100 N.
21.A book of 1.0 kg slides freely across a long table with an initial speed of 10 m/s. It comes to a stop after 5 m.What is the magnitude of the force of friction acting on the book?a.5 Nb.10 Nc.15 Nd.20 N
