WQ6.2 6/6 points (graded) Suppose the bricks are pushed by the hand with the same force as before (in WQ6.1); however the table has less friction and the coefficient of kinetic friction between the bricks and the table is less than in WQ6.1. Hand 1 8 a) Describe the motion of systems A and B. How does the motion compare to the situation in WQ6.1? The motion is now faster constant speed C same constant speed C slower constant speed > not a constant speed b) Compare the magnitude of the net force on system A (two bricks) to that on system B (one brick) OFnet,A = Fnel,B Fnet,A > Fnet,B V OFnet.A <ÂŞnet,B c) Explain your answer for b): zero net force V d) Consider the horizontal forces that act on the two systems. Compare the following forces and complete the two statements below.
d)i) The friction on B is the normal force A exerts on B. C greater than smaller than the same as *not enough information to answer d)ii) The friction on A is the normal force B exerts on A. greater than C smaller than the same as 'not enough information to answer > e) Explain your answer for d): not enough info V
