Practice Activity
1) Calculate the normal force exerted by the ground
(34 kg) * 9.81 m/s2 = 333.5 N (vector in the direction of arrow 1)
2) Calculate the weight of Bogey (the Putter Prince)
(34 kg) * 9.81 m/s2 = 333.5 N (vector in the direction of arrow 2)
3) Calculate the net force on the golf club when the ball is struck
45 g / 1000 = 0.045 kg
0.045 kg * 7 m/s2 = .315 N (vector in the direction of arrow 4)
4) Calculate the net force on the golf ball when the ball is struck
0.045 kg * 7 m/s2 = .315 N (vector in the direction of arrow 3)
