Answer

Use the slingshot to shoot the rock horizontally from a height of 1 meter. The 1-meter vertical displacement of the rock is related to the time of flight by equation 2.11b, and is 0.45 seconds. Next, measure how far the rock moved horizontally, R. We know that R = v(0.45 s), so solve for the horizontal velocity v.

Work Step by Step

One can determine speed here using known values (vertical displacement) and measuring distance and time.
