EPHYSL:Physicsfor Engineers-LaboratoryActivity: Projectile MotionOBJECTIVE:To study the motion of aprojectile.THEORY:Read theory here:PROCEDURE:Part 1.1.Go to :2.Set the initial speed of the cannon, found at the lower left side of the screen, to AB m/s. Keep thisvalue constant.where:A = 1 if the number of letters of your first name is even= 2 if the number of letters of your first name isodd B = the number of letters of your familyname.3.Set the mass of the cannonball to 15 kg, diameter to 0.15m and gravity to 9.81 m/s2found on the right side of the screen.4.Set the cannon at an angle of 25, fire by clicking the iconand note the approximate place where theballstrikes the ground.5.Measure the range, R, and total time of flight, T, by dragging the point and measure icon where theball landed and record the data.
Click here to drag6.Record the maximum height, H, reached by the ball and the time, t, for the ball to reach thatpoint. 7.Repeat 4 and 5 by changing the angles to 30, 35, 40, 45, 50, 55, 60, 65, 70,75, 80, and 85.
