Question a)

 Instructions: Set the cannon's angle to 25 degrees and keep adjusting the velocity until you hit the target. Do the same for 45 degrees and 65 degrees. Record your results in the chart.

Summary of Results:

 Angle Velocity(m/s) 25 45 65

 Instructions: Set the cannon's velocity to 50 m/s and do not change it at any point in this experiment. Experiment to see how the size of the cannon's angle of trajectory effects the size of the projectile's maximum horizontal and vertical displacements (range and  height).

Question b)

I ) Summarize how the size of the cannon's initial angle of trajectory affects the sizes of the projectile's horizontal and vertical displacements (height and range)

Complete these sentences

Increasing the cannon's angle from  2 to 10 to 45 degrees causes the size of the horizontal displacement to ________________and causes the vertical displacement to _____________.

Increasing the cannon's angle from 45 to 65 to  85 degrees      causes the horizontal displacement to _______________ and the vertical  displacement to _______________

II) Which angle produces the largest horizontal range and which angles the greatest vertical range?
