Calculations & Work Written Between the Sentences of the Problem is NOT Scored 3) As shown, two physics students on rollerblades are about to make an elastic collision on a surface whose frictional forces may be neglected. Cindy (of mass 40.0 kg), moves to the right at +6.0 m/s and collides with Steve (of mass 60.0 kg) who is initially at rest. (19 points) (a) At the moment Cindy collides with Steve, what is the direction of the impulse she exerts on him? (1 point) Left Right Cindy (b) At the moment Cindy collides with Steve, what is the direction of the impulse he exerts on her? (1 point) Left Right Steve (c) Calculate the speed of Cindy the moment after the collision. (3 points) (d) The moment after the collision, in which direction does Cindy move? (1 point) Left Right (e) Calculate the speed of Steve the moment after the collision. (3 points) (f) The moment after the collision, in which direction does Steve move? (1 point) Left Right (g) With appropriate calculations, prove that this collision is elastic. (4 points) (h) Calculate the magnitude of the impulse on Steve caused by Cindy. (2 points) (i) Suppose the time of the collision is 0.100 second. Calculate the magnitude of the average force Cindy exerted on Steve (give your answer in both Newtons and in pounds, where 1.0 N=0.22 pound). (3 points)
