Which statement describes the velocity of a mass oscillating on a spring? a. the velocity is constant throughout the motion. b. the velocity remains the same throughout the motion. c. the velocity is zero at the maximum displacement. d. the velocity is greatest at the maximum position. e. the velocity is least at the equilibrium position.

velocity of to and fro motion of an object connected to a spring is given as

so here we can see that velocity will be maximum when its displacement will be minimum

so here at x = 0

maximum velocity will be

as well as the velocity is not uniform and it will decrease as object moves away from its mean position

so here correct answer will be

C. The velocity is zero at the maximum displacement.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
