3. A person kicks a soccer ball at an angle and sends it in the air.
a) What angle of projection between 0 and 90 degrees produces the greatest initial vertical component? _____
greatest initial horizontal component? ____
b) A soccer ball is kicked at a speed of 8
m/s. Circle the angle below that will give the ball the largest (dy)?
Which angle will make the ball go the farthest (dx)?
13 degrees 7 degrees 40 degrees 85 degrees 2 degrees.?
4.What angle can you kick a football that
will the make the initial vertical component of the velocity equal to the
initial
horizontal
component
of the velocity? ____
5. Name an angle that you could kick a
football that would give it a very large initial vertical component
but a small
nonzero initial
horizontal component. _____
6. How would the vertical component
of a velocity change if the angle of projection was changed from 80 degrees
to 60
degrees? _____
7. A soccer ball was kicked on a horizontal field. The initial vertical component of the soccer ball was +15 m/s and the initial horizontal component was + 8 m/s.
a) What was the vertical component of the balls velocity just before it hit the ground? ______
b) What was the horizontal component of the balls velocity just before it hit the ground? ______
