Ulysses stood on top of the force plate with feet hip to shoulder width apart hinging at the hips until their hands reach the bar. Afterwards, the he performed an isometric mid-thigh pull contracting as hard as possible for 3 seconds. Ulysses proceeded to do this for a total of three trials. First pull they generated 4000 Newtons (ground reaction force), second was 4250 Newtons, and third was 4200 Newtons. Discussion 1. Explain Newton's first law and give a detailed example of it. 2. If someone is lifting a barbell that weighs 45 lbs, how much force is needed to accelerate it upwards in newtons? Explain. 3. Calculate the average ground reaction force from the force plate. 4. Does this ground reaction force demonstrate Newton's third law? Explain.
