1. The problem statement, all variables and given/known data How do i compute theoretical acceleration and experimental acceleration? 3. 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?
