[QUOTE="santoki, post: 4678353, member: 502242"] [B]Question:[/B] A soccer player kicks the ball off the ground at an angle Θ above the horizontal. The ball is in the air for 3.0 seconds and lands 40 m away (assume the field is level). a) Make a table of x and y components and fill out what you know, based on the problem statement above, and your knowledge of kinematics (don’t calculate anything yet). Draw a box around your table. b) Now work outside of the box. Find the soccer ball’s initial horizontal (vox) velocity component. c) Find the soccer ball’s initial vertical (voy) velocity component. [B]Attempt:[/B] a) x-component [LIST] [*]d = 40m [*]t = 3s [*]v[SUB]o[/SUB] = 0m/s [*]a = 0m/s[SUP]2[/SUP] [/LIST] y-component [LIST] [*]a = 9.8m/s[SUP]2[/SUP] [*]t = 3s [*]v = 0m/s [/LIST] b) d = vt 40 = 3v v = 13.3m/s c) v = v[SUB]o[/SUB] - gt v = 0 - (9.8)(3) v = -29.4m/s am I on the right track or am I supposed to find that missing angle?
