Question

Problem 2: Setup an Atwood machine using a pulley, string and two masses. Measure the acceleration of the masses when released from rest and compare to the theoretical value as calculated in Lesson notes. By measuring the elapsed time, and the vertical displacement ?y, the acceleration aexp is determined using ?y = v1t + 1/2aexpt². Compare the measured and theoretical values of a using the percent error formula (see Lesson 6 for atheory). Table 1: Experimental Data Mass | m1 (kg) | m2 (kg) | ?y (m) | t (s) | aexp (m/s²) | atheo (m/s²) | %E m1 = m2 m1 ? 2m2 Note: The symbol ? means “approximately equal to”.
