A curling rock moving at 28.0 cmis makes a glancing collision with a stationary second curling rock of equal mass. After the collision the first rock moves at 18.0 cmfs at 47.0\" from the initial direction. A Question 3 (1 point) Retake question (a) Determine the speed of the second rock. Your Answer: Answer units A Question 4 (1 point) Retake question (b) At what angle does the second rock move? Enter your answer as the number of degrees from the positive x-axis. If you find an angle that is greater than 180 D from the positive x-axis, instead enter a negative answer to represent an angle that is below the positive x-axis
