I didn't have a video camera so I am going to use the pictures and solve for acceleration.
When the car accelerated it created a 70 degree angle on the accelerometer.
We can draw a force diagram and then solve from there.
To solve for tension just use the formula: sin70=5/t
t=6.5N
We can now solve for Funbal by using the Pythagorean theorem
Funbal^2 + 5^2 = 6.5^2
F^2 = 17.25
F = 4.15N
Now we can find the acceleration using the formula: a=Funbal/M
a=4.15N/.5kg
a=8.3m/s^2
