High-speed stroboscopic photographs show that the head of a golf club of mass 220 grams is traveling at 50 m/s just before it strikes a 46-gram golf ball at rest on a tee. After the collision, the clubhead travels (in the same direction) at 36 m/s. Find the speed of the golf ball just after impact. Is the collision between the clubhead and the golf ball elastic or inelastic. Why

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.

M1 = 2.8 kg, m2 = 6.72 kg, m3 = 11.2 kg, byas in .is ,is .toof m3 it 0.91 m. (in m/s)
