Exercise 7

One mass, m 1 = 0.215 kg, of an ideal Atwood machine (see Fig.) rests on the floor 1.10 m below the other mass, m 2 = 0.255 kg. (a) If the masses are released from rest, how long does it take m 2 to reach the floor (b) Flow high will mass in m 1 ascend from the floor ( Hint : When m 2 hits the floor, m 1 continues to move upward.)
