High - speed stroboscopic photographs show that the head
of a 2.00 x 102 - g golf club is traveling at 55.0 m/s just before it
strikes a 46.0 - g golf ball at rest on a tee. After the collision, the
club head travels (in the same direction) at 40.0 m/s. Find the
speed of the golf ball just after impact.

Expert Answer

Step 1

Given data:

Mass of the golf club, M = 200 g = 0.2 kg

Speed of the golf club, u1 = 55.0 m/s

Mass of the golf ball, m = 0.046 kg

Speed of the golf ball, u2 = 0 m/s

Final speed of the golf club, v1 = 40.0 m/s

Let the speed of the golf ball just after the impact be v2.

Step 2

From the conservation of momentum:

Total initi...
