Part C: Predicting the Range of the Ball Shot at a Negative Angle
➀
Adjust the Mini Launcher to launch at an angle between 10 and 40 degrees below the
horizontal and record this angle in Table 1.3.
➁
Using the initial velocity and vertical distance found in the first part of this experiment,
calculate the new time of flight and the new horizontal range for a projectile launched at
the new angle. Record in Table 1.3.
➂
Draw a line across the middle of a white piece of paper and tape the paper on the floor so
the line is at the predicted horizontal distance from the Mini Launcher. Cover the paper
with carbon paper.
➃
Shoot the ball ten times.
➄
Measure the ten distances and take the average. Record in Table 1.3.
Analysis
➀
Calculate the Total Average Distance. Record in Table 1.3.
(Total Average Distance = Distance from Edge of Paper + Horizontal Distance to paper
edge)
➁
Calculate and record the percent difference between the predicted value and the resulting
average distance when shot at an angle.
➂
Estimate the precision of the predicted range. How many of the final 10 shots landed
within this range?
