if the 1kg standard body an acceleration of 20.0° to the postive direction of an x axiis : a) what are the x and y compnonents of the net force acting on the body . b) what is the net force in unit-vector nation

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.
