A golf ball of mass 0.045 kg is hit off the tee at a speed of 48 m/s. The golf club was in contact with the ball for 5.4 10-3 s.

(a) Find the magnitude of the impulse imparted to the golf ball.

(b) Find the magnitude of the average force exerted on the ball by the golf club.

2 answers

Impulse= mass*changeinvelocity
Force*time= Impulse solve for avg force.
a)
J=m*(change)v
J=0.045kg*48m/s
J=2.16kg*m/s

b)
J=F*t
F=J/t
F=2.16kg*m/s/5.4*10-3s
F=400N
