3: In the figure below, when an athlete is walking at a normal pace with, a = 10,8 m/sec ^2 acceleration, the swing start phase is given during walking, and when one foot touches the front (heel strike phase), the other foot is cut off from the ground (toe off phase). Calculate the angle, e, between the two legs during). Below, the athlete walking at a normal pace shows the initial swing phase of one leg, the heel and sole of the front foot on the ground, and the head of the rear foot. defined and given as the moment when the finger was cut off from the ground. Also, calculate the reaction force that the swinging leg will exert on the hip joint. Let the total mass of one leg be m = 32 kg, gravitational acceleration, g = 9,81m/sec ^2 20 Toe-off

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
