A golf ball of mass 0.050 kg is at rest on the tee. Just after being struck, it has a velocity of 102 m/s. If the club and ball were in contact for $0.81 \mathrm {~ms}$ what is the average force exerted on the ball by the club?
A) 6.3 kN
B) 7.1 kN
C) 5.5 kN
D) 4.9 kN

The average force can be calculated using the impulse-momentum theorem: $ F \Delta t = m \Delta v $. Here, $ m = 0.050 \, \text{kg} $, $ \Delta v = 102 \, \text{m/s} $, and $ \Delta t = 0.81 \, \text{ms} = 0.00081 \, \text{s} $. Solving for $ F $, we get $ F = \frac{m \Delta v}{\Delta t} = \frac{0.050 \times 102}{0.00081} = 6.3 \, \text{kN} $.
