calculate the terminal velocity of a 1-cm bug. assume that the density of the bug is 1 g/cm3 and that the bug is spherical in shape with a diameter of 1 cm. assume further that the area of the bug subject to air friction is 丁τ r 2

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
