A 70 kg bicyclist is riding her 15 kg bicycle downhill on a road with a slope of 80 without pedaling or braking. The bicyclist has a frontal area of 0.45 m2 and a drag coefficient of 1.1 in the upright position, and a frontal area of 0.4 m2 and a drag coefficient of 0.9 in a racing position. If the downhill speed of the bicyclist (terminal velocity) can be determined when the total force acting on the “body” in the direction of movement is equal to zero, determine the percentage of down
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.
