**Question:**

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.

**Attempt:**

a)

x-component

- d = 40m
- t = 3s
- v
_{o}= 0m/s - a = 0m/s
^{2}

- a = 9.8m/s
^{2} - t = 3s
- v = 0m/s

b)

d = vt

40 = 3v

v = 13.3m/s

c)

v = v

_{o}- 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?
