When a spherical body goes by a viscous fluid, it feels a viscous force. The value of the viscous force increases with the enhance in speed of the object falling under the function of its weight. As a result, the viscous force soon becomes the driving force and the object starts rolling with a constant speed, called as its terminal velocity. Let us now produce a relation for the terminal velocity, as an application of stokes' principle.
A 1.6 kg man swings from a 2 meter rope at an angle of 45 degrees after swinging 20 degrees past the center point, the rope is cut by a razor. The man goes flying through the air
