Be sure air resistance is off and spend some time firing various projectiles. Set the initial speed to a value between 10-15m/s. Choose your favorite projectile. Find the range of the projectile at various angles. 0 = 30 Range (dx) = m 0 = 70 Range (dx) = m 0 = 40 Range (dx) = m 0 = 80 Range (dx) = m 0 = 50 Range (dx) = m Add two A = Range (dx) = m more > 0 = 60 Range (dx) = m A = Range (dx) = m Measure the distance from the cannon to the target using the tape measure. Move the target to 21.0 m from the cannon. Attempt to hit the target with three different angles by changing the firing angle and initial velocity. Range (d ) = 21.0m 0 = Vi = Range (dy) = 21.0m 0 = Vi = V V ......... V y
