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
