Homework Statement
How do i compute theoretical acceleration and experimental acceleration?
The Attempt at a Solution
For the first sets of data, the experimental equation, i first averaged the timings.
Then i used:
s = ut + 0.5at^2, where u=0
0.7 = 0.5*a(2.11seconds)^2
a = 0.3144 m/s^2
but for theoretical acceleration, this is what i did.
m1 * g - T = m1 * a (eq 1)
T = m2 * a (eq 2)
Sub 2 into 1:
m1g - m2a = m1 * a
m1g = m1a + m2a
m1 g = a(m1+m2)
a = m1g/(m1+m2)
a = (0.307*9.81) / (0.307+0.011) = 9.47m/s
Where did i go wrong?
