Question

You will be using the launcher shown at the right to shoot a ball. It can be rotated to shoot the ball at any angle. The launching position where the ball leaves contact with the launcher is marked by a white circle on the side of the launcher with the same diameter as the ball. The circle is also shown below. You will put carbon paper under white paper on the table to make a mark where the ball lands each time. Consider the position of the ball when it lands.

a) To find how far the ball has fallen vertically from the launch position when it lands on the table, do you want to measure the height from the center or the bottom of the circle to the table? Explain.

b) To find how far the ball has moved horizontally where on the circle do you want to measure from?

Explanation / Answer

a)

To find how far the ball has fallen vertically from the launch position when it lands on the table, We need to measure the height from the center of the circle to the table, since the center of mass of the ball would be concentrated at the centre.

b)

This is done from the outer edge of the circle as the horizontal distance travelled is obtained from this point till it leaves a mark
