PLEASE ANSWER so what’s the difference between free fall and someone actually sky diving?:

a)- MUST use the terms (velocity) (force) (acceleration) (g) (free fall) (terminal velocity)

b)- include concepts force due to gravity, force due to air resistance, acceleration due to gravity !!

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?

The strong nuclear force acts over a small distance than the electrostatic force. true or false
