Homework Statement
Hi, I am doing a projectile motion lab for two dimensional kinematics. After completing the procedure of the lab, I have 3 graphs where
Y vs. X has a slope of y = -0.0037x2 + 0.9169x + 0.2684
X vs. T has a slope of y = 373.95x + 3.4011
Y vs. T has a slope of y = -505.11x2 + 328.29x + 3.5949
From the graphs, I have to figure out
ay (cm/s^2)
vx (cm/s)
v0y (cm/s)
angle (degrees)
Homework Equations
ax (t) = 0
ay (t) = -g
vx (t) = v0x
vy (t) = voy + ayt
x(t) = x0+v0xt
y(t) = y0+v0yt+1/2ayt^2
Change in angle = (vy^2*change in vs^2 + vx^2 + change in vy^2)/(vx^2 + vy^2) * (180/pi)
The Attempt at a Solution
vx = 373.95 +/- 3.4011
But for voy, and ay, the equations say that I need to use a specific time to find the answer, which I do not have according to the graphs.
Any suggestions on how to obtain the other two (ay, v0y) would be greatly appreciated.
From there I know I can find the angle by plugging all the components into the "change in angle" equation given above.
Thanks all.
