Calculate the vertical lifting force F required in each case. Assume your mass is 72 kg, that your hands are 1.5 m from your toes, and that your center of gravity is 1.15 m from your feet. It seemed like it might be a good idea for each of you to go through this calculation again. A shot putter holds a 178 N ball in his hand. The forearm weighs 22 N and the center of gravity is located 8.9 cm from the elbow.
All distances shown are relative to the elbow.
There are three forces acting on you and your center of gravity is 1.1 m from your feet. A car of mass 1750 kg has its center of mass located 0.6 m behind the front axle. The rear axle is 2.2 m behind the front axle.
