A stone is thrown horizontally from the top of a building. It has an initial speed of 5m/s2. Use g= 10m/s2. The height of the building is 50m. The ground is at the base of the building. a) Define your initial conditions at t=0 in the following:
xi= yi= (Vx)i= (Vy)i=

b) Find the time the stone stays in the air

c) find the range (Xf-Xi) of the stone:

d) find the speed of the stone at the landing

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.
