Question

A golfer hits a 0.050 kg golf ball, giving it a speed of 78 m/s. What is the impulse imparted to the golfball?

Answer 1

Answer:

3.9kgm/s

Explanation:

Given parameters:

Mass of the golf  = 0.05kg

Speed  = 78m/s

Unknown:

Impulse imparted to the golfball  = ?

Solution:

Impulse is the change in momentum of a body;

  Impulse  = m (v  - u)

m is the mass

v is the final speed

u is the initial speed  = 0m/s

So;

         Impulse  = 0.05 (78 - 0) = 3.9kgm/s
