Question

A golf ball has a mass of 46 grams, and when struck by a driver reaches a speed of 42 m/s in a time of 0.00050 seconds. what was the impulse, in n s, generated by the golf club?

Answer 1

Impulse in physics is the integral of force, F, with respect with time, t. This value is a vector quantity since force is a vector quantity as well. It can be calculated from the product of force and time. We do as follows:

Impulse = Ft
               = m(a)(t)
               = m(v/t)t
               = 0.046 (42/0.0005) (0.0005)
               = 1.932 N-s
