Document Summary
Solve the following problems in the space provided. Use the back of the page if needed. You must show your work in a logical fashion starting with the correctly applied physical principles. The equations you need are on the equation sheet. Your score will be maximized if your work is easy to follow because partial credit will be awarded: a soccer ball is kick with a speed of 18. 0m/s at a 30. 0 angle above the horizontal. Find (a)the time it is in the air and (b)the distance it travels before it hits the ground. y vo (a)using the kinematic equation along the y-axis, y = y o + v oyt + 1. Putting in the things that are zero and solving for t, 0 = 0 + v oyt + 1. # t = 1. 84 s . (b)using the kinematic equation along the x-axis, x = x: + v ox t + 1.
