5. A ball is thrown following a projectile motion. It is known that the horizontal distance (range) the ball can travel is given by R Do sin 20, where r is the range (in %3D feet), vo is the initial speed (in ft/s), 0 is the angle of eievation the ball is thrown, and g=32 ft/s? is the acceleration due to gravity. a. Express the new range in terms of the original range when an angle e (0< 8< 45°) is doubled. b. If a ball travels a horizontal distance of 20 ft when kicked at an angle of a with initial speed of 20/2 ft/s, find the horizontal distance it can travel when you double a. od neb 1ertu Hint: use result of item (a).

Ruth sets out to visit her friend Ward, who lives 60 mimi north and 100 mimi east of her. She starts by driving east, but after 20 mimi she comes to a detour that takes her 15 mimi south before going east again. She then drives east for 8 mimi and runs out of gas, so Ward flies there in his small plane to get her. 1. What is Ward's displacement vector? Give your answer in component form, using a coordinate system in which the y-axis points north. 2.What is the magnitude of Ward's displacement vector? 3. What is the direction of Ward's displacement vector?
