A 75-kg skydiver jumps from an airplane at an altitude of 5.0 ✕ 103 m, falling in a headfirst position. (a) Make a reasonable estimate of his cross-sectional area. (b) Calculate his terminal velocity. (c) How long will it take for him to reach the ground (assuming the time to reach terminal velocity is small)? (Assume his drag coefficient to be C = 0.70.)
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.
