The vertical jump height of Michael Jordan (a famous NBA player) is 122cm during his career as a player. His body height is 1.98m. His body weight was 98kg in that same period. Assume that the force his legs act on his body is constant. Also assume that when standing, the height of his center of gravity is half of his body height, and that when he bends his legs at the starting position of jump, his center of gravity decreases to half of the value of standing. (a) Estimate the force that his legs act on the floor, and (b) estimate the duration of the acceleration.
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
