When an unknown weight W was suspended from a spring with an unknown force constant k it reached its equilibrium position and the spring was stretched by 58.6 cm because of the weight W . Then the weight W was pulled further down to a position 71 cm (12.4 cm below its equilibrium position) and released, which caused an oscillation in the spring. Calculate the cyclic frequency of the resulting motion. The acceleration due to gravity is 9.8 m/s 2 . Answer in units of Hz.

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.
