wheels (with the masses concentrated at the
rims). the left wheel has a mass of 2.5 kg and
radius 22.2 cm. the right wheel has a mass
of 2.7 kg and radius 27.49 cm. the hanging
mass on the left is 1.59 kg and on the right

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
