15. If a projectile is launched upward with a speed of 39.1 m/s, and at an angle of 10.4\" above horizontal, what is the range of this projectile? 16. Carrie is going for a morning run on the deck of a cruise ship. Using the ship as her frame of reference, she is running east at a speed of 2.76 m/s. If the ship is traveling north at a speed of 9.38 m/s, what is Carrie's velocity with respect to a stationary point on the water? Application For a group project, a team of physics students is trying to develop a device that can launch marbles so that they land in a predictable location every time. 17. The current version of the device applies a 1.81 Newton force to the marble at an angle of 51' above horizontal. What are the horizontal and vertical components of this force vector? 18. The students are not getting the marbles to travel as far as they would like. What are some changes they could make to the device so that they get a greater range? Go on to next page 19. The current setup of the device launches the marbles at a speed of 9.05 m/s. If the students adjust the launch angle from 51" to 35', what effect will this change have on the marbles' hang times? 20. During one launch, when the 4.0-gram marble is at the peak of its trajectory, moving to the right, the only forces acting on it are the force of gravity, and a 0.01 N force of drag to the left. Draw the free body diagram for this situation. 10. 11. 12. 13. 14. Louisa and Tam are driving in a car. Thev travel 450 m at a heading of 15 south of west, then 230 m at a heading of 36 south of west. What is their final displacement vector after the second leg? A round stone rolls towards the edge of 21 meter cliff. As it reaches the edge of the cliff, it is moving forward with a speed of 5.7 m/s. How far, horizontallv, from the cliff face will the rock land? Stacv uses a giant sling shot to launch a water balloon at an angle of 27 above horizontal. If the speed of the balloon is 19.7 m/s, what are the horizontal {x} and vertical {v} components of the initial velocitv? A tee-shirt cannon is used to launch tee-shirts into a crowd. If one shirt is launched with an initial velocitv of 24.4 m/s. at an angle of 19.5\" above horizontal, what will be the x- and v-components of the final velocitv vector? If a projectile is launched upward with a speed of 7.44 m/s, and at an angle of 40.1\" above horizontal, what is the hang time of this projectile? Go on to next page
