You will be given the initial speed of the steel ball (or perhaps you'll have to devise a way to measure it). Record the firing speed here. Horizontal speed v = 6.5 m/s Step 2: Carefully measure the vertical distance y that the ball must drop from the bottom end of the ball projector in order to land in an empty soup can on the floor. Be sure to take the height of the can into account when you make this measurement. Vertical distance y = m Step 3: The vertical free-fall motion is governed by the equation y = (1/2)gt". A rearrangement of the equation, t = ā(2y/g), enables you to calculate the time it takes the ball to fall from its original height. For gravitational acceleration, use g = 980 m/s". Time of flight t = s Step 4: The range is the horizontal distance a projectile travels, x. Predict the range of the ball using x = vt. Write down your predicted range. Predicted range x = m Now place the can on the floor where you predict it will catch the ball. Step 5: Only after your instructor has checked your predicted range and your can placement, shoot the ball. Summing Up 1. Did the ball land in the can on the first trial? If not, how many trials were required? 2. What possible errors would account for the ball overshooting the target? 3. What possible errors would account for the ball undershooting the target? 4. If the can you used were replaced with a taller can, would you get a successful run if the ball started with a higher speed, a lower speed, or the same speed? Explain.
