Question

Here is the data collected from my projectile motion and conservation of energy lab on an even plane. The Theoretical range that I calculated was R=1.68. I am to GRAPH Range vs. Initial launch angle and then CALCULATE the % difference between the measured range(?) and the theoretical range (1.68) for the initial launch angle of 45 degrees. PLEASE show work

Table 3: Even y Plane ; = 45 AX1 AX2H AXSH

Answer 1

	$\Theta$=450
$\Delta x_1$	106.5
$\Delta x_2$	107.0
$\Delta x_3$	107.5
$\Delta x_4$	108.0
$\Delta x_5$	108.0
$\Delta x_{avg}$	107.4

$\frac{\Delta x_{avg}}{\Theta =45^{0}}=\frac{107.4}{45}=2.386$

$\frac{\Delta x_{th}}{\Theta =45^{0}}=1.68$

$Percentage.Relative . Error =\frac{2.386-1.68}{1.68}*100=42.1$%
