Question 7 2 pts Complete the following statement: The net force that results when two or more forces act on an object is " determined by adding the magnitudes of the individual forces. The direction of the net force is the same as the direction of motion. " the largest force acting on the object. ' the magnitude of the largest force acting on the object. The direction of the net force is the same as the direction of motion. " determined using vector addition of the individual forces acting on the object. Question 4 3 pts A y-QZIS 10 + II P(3.5) 5-.... a...... -aris -10 10 (0,0) -5+ origin III IV -10+ Two vectors given are r1 = 2i + 4j, and r2 = -5i + 6j. If the displacement, Ar, happens in 0.2 seconds, find the average velocity v. O v = Ar/At = -35i - 10j O v = Ar/At = 7i - 2j O v = Ar/At = -35i + 10j O v = Ar/At = 7i + 2jQuestion 12 3 pts Complete the following statement: Frictional forces and drag forces _________________ ' oppose motion only because of contact surfaces and area of the object " oppose the motion due to the density of the object ' oppose the motion due to the mass of the object ' oppose the motion due to the inertia and due to the volume of the object ' oppose the motion due to the weight of the object
