Unit A Module 2, Lesson 4: Projectiles in Two Dimensions Lesson 2 of this assignment is worth 15 marks. The value of each question is noted in the left margin in parentheses. 5. Use the information below to answer parts af. Show all your work including vector diagrams, formulas, etc. A soccer ball is kicked at an angle of 320 above the horizontal With an initial velocity of 25.0 m/s. a) Determine the horizontal component of the initial velocity. b) Determine the vertical component of the initial velocity. c) What is the ball's horizontal velocity at 2.00 s? d) What is the ball's vertical velocity at 2.00 s? e) What is the horizontal displacement at 2.00 s? (1) f) What is the vertical displacement at 2.00 s? (1) 6. Use the following information to answer parts ab. Assume air resistance is negligible and show all work. Tiger Woods' golf balls leave his club with an average speed of around 76.0 m/s. He hits a ball with an angle of 15.0 relative to the horizontal. a) How long is the golf ball in the air? (3) b) Does the acceleration ever become zero? If so, explain at what location during the motion this occurs and at what time on the graph. c) Does the vertical component of velocity ever become zero? If so, explain at what location during the motion this occurs and at what time on the graph. You're done! Once you've completed and checked all of your solutions, submit all of Assignment 4 to the appropriate dropbox in Moodle. b) What is the horizontal displacement of the golf ball?
