Unformatted text preview: As a result, we will use the appropriate significant digits so as to demonstrate our uncertainty. By shooting the ball at an angle of zero, we limit the initial speed on the ball to its x component. If the launch angle is 30, we will have to calculate the x component of the ball using trigometric equations. Instead, we should use a zero launch angle when measuring the initial speed of the ball because the horizontal speed will simply be the distance it travels horizontally over the time it takes before it hits the ground....
