A soccer ball kicking machine is designed as shown. The pendulum used

A soccer ball kicking machine is designed as shown. The pendulum used to kick the ball has a mass of m, with the centre of mass at point G, and a radius of gyration about the centre of mass of kg = 340 mm. The setup is released from rest at an angle = 40. Determine the suitable mass, m of the pendulum to achieve an angular velocity of w = 6 rad/s just before it impacts the ball. The spring constant is k 170 N/m, and the spring has an unstretched length of 30 cm. 60 cm = 65 cm 0 wwwww wwwwwwwww k = 170 N/m 95 cm
