The masses in an Atwood machine are 15 kg and 2.5 kg (See the figure). If the masses
are at a height of 1.25 m when the system is
released
a) how many seconds does it take for the
greater mass to reach the ground?
b) What is the velocity of the smaller mass

c) If this experiment were
carried out on the Moon, how
