➃
Tape a piece of white paper to the board in the region where the ball is hitting. Then
cover the white paper with a piece of carbon paper.
Procedure
➀
Shoot the ball at various angles and pinpoint exactly which angle gives the maximum
height by checking the marks on the paper.
➁
Measure the angle that produces the maximum height and record in Table 7.1.
➂
Measure the maximum height and record in Table 7.1.
➃
Measure the horizontal distance from the muzzle to the vertical board and record in
Table 7.1.
➄
Measure the initial height of the ball where it leaves the muzzle and record in Table 7.1.
Analysis
➀
Calculate the initial velocity by solving the y-equation for v
0
and plugging in the values
from Table 7.1.
➁
Calculate the angle for maximum height using the initial velocity calculated in Step 1
and the horizontal distance from the wall to the launcher.
➂
Calculate the percent difference between the measured angle and the calculated angle.
Questions
➀
For the angle at which the ball strikes the wall at the maximum height, has the ball
already reached the peak of its trajectory when it strikes the wall?
➁
How far from the wall would you need to place the launcher so that when the ball is
launched at 45° it strikes the wall at a maximum height? What would the maximum
height be in this case?
