Question 1 of 10 Score: 1 (of possible1 A bowling ball is rolled towards a set of pins. The bowling ball hits seven pins and knocks them over. What must happen to the bowling ball during this collision?point)A.It will transfer momentum to the pins, causing it to slow downB.It will take momentum from the pins, causing it to speed upC.It will not be affected by the pins, and will maintain the same velocity.Answer Key: AQuestion 2 of 10 Score: 0 (of possible1 Two objects must be in physical contact with each other in order for a collision to occur. point)
Question 3 of 10 Score: 1 (of possible1 THE SITUATION BELOW APPLIES TO THE NEXT FIVE QUESTIONS (QUESTION 3, 4, 5, 6, AND 7):Most materials in life are partially inelastic. Do the following items tend to be more elastic, or inelastic?Pool ball striking pool balls:point)Question 4 of 10 Score: 1 (of possible1 Ping pong ball striking the table:point)
Question 5 of 10 Score: 1 (of possible1 Ball of spit hitting the sidewalk:point)A.more elasticB.more inelasticAnswer Key: BQuestion 6 of 10 Score: 1 (of possible1 A meteor striking the atmosphere:point)
Question 7 of 10 Score: 1 (of possible1 A satellite getting a gravity assist from Jupiter:point)Question 8 of 10 Score: 1 (of possible1 THE SITUATION BELOW APPLIES TO THE NEXT TWO QUESTIONS (QUESTION 8 AND 9):Consider the collision of two balls, one with mass m1= m and a second with mass m2= 2m. Initially the lighter ball moves with speed v1iand the second is at rest. The collision all happens in one dimension; along a straight line.If the collision between these balls is perfectly inelastic, what is the final speed of the combined object after the collision?point)
Question 9 of 10 Score: 1 (of possible1 Imagine the same collision again, this time it happens elastically, with all the kinetic energy conserved. What is the final speed for mass m2?Note that this is worked out in your lecture notes for the general case. You just have to apply what's there.point)A.3*v1iB.2/3*v1iC.v1iD.1/2*v1iAnswer Key: B
