A golf club makes impact with a 0.045 kg golf ball during a drive off the tee. The loft angle of the club (the angle between the club face and vertical) is 10 degrees. The normal contact force exerted by the club on the ball is a 7500 N force directed forward and upward 10 degrees above horizontal. The friction force exerted by the club on the ball is 700 N directed forward and downward 80 degrees below horizontal.
a. What is the magnitude of the vector sum of the two club head forces acting on the golf ball? (Answer: 7533 N) Need to show work.
b. What is the direction of this resultant force? (Answer: 5 degrees forward and upward above horizontal) Need to show work.
