Aprojectile is shot from the edge of a vertical cliff 60.0 m above the ocean. it has a speed of 100 m/s and is fired at an angle of 35.0° below the horizontal. how far from the foot of the vertical cliff does the projectile hit the water?

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.
