You will use this problem for Questions 8 and 9.  Read carefully!   In physics class, two “frictionless” carts are placed on a track.  The first cart (m1 = 0.620 kg) is pushed to the right with a speed of 4.5 m/s.  The second cart (m2 = 0.790 kg) is pushed to the left with a speed of 1.8 m/s.  If the first cart rebounds with a speed of 0.9 m/s, Q8:  find the speed and direction of the second cart. Q9:  Determine whether the collision is elastic or not.  You must show your work for full credit!   For this question, enter the answer to Q8.

You will use this problem for Questions 3 and 4.  Read carefully!   A basketball, mass 0.62 kg, falls straight down and strikes the floor with a speed of 35 m/s and rebounds straight up with a speed of 27 m/s.  If the ball is in contact with the floor for 0.075 seconds, Q3:  find the magnitude of the average force exerted on the basketball. Q4:  How much kinetic energy was lost during the bounce? For this question, enter the answer to Q3.
