The gure below shows an Atwood machine with two masses (m1 and m2) initially at rest at the same height. After they are released, the large mass, m2, fails a distance h and hits the floor, while the small mass, m1, rises the same distance h. 'l h .1 (a) Find the speed of the masses just before m2 lands. Assume the ropes and pulley have negligible mass and that friction can be ignored. (Use any variable or symbol stated above along with the following as necessary: 9 for the acceleration due to gravity. Do not substitute numerical values; use variables only.) V: (b) Evaluate your answer to part (a) for the case where h = 1.24 m, m1 = 3.10 kg, and m2 = 4.30 kg, m/s
