5. An Atwood machine consists of two masses m1 and m2 (with m1 > m2) attached to the ends of a light string that passes over a light, frictionless pulley. When the masses are released, the mass m1 is easily shown to accelerate down with an acceleration m1 'm2 (1: gm1+m2 Suppose that m1 and m2 are measured as m1 = 98 -|_- 1.0 grams and m2 = 73 i 0.90 grams. Derive an equation for the uncertainty in the expected acceleration in terms of the masses and their uncertainties, and then calculate a i 66: for the given numbers. You do n_ot have to simplify your uncertainty equation. m: is there hidden correlation
