Consider a mass m connected to a horizontal spring with spring constant k. ignore friction between mass and surface. let be the displacement from equilibrium (a) obtain an expression for the speed of the mass as a function of k, m, and the initial position ro and speed (b) use the expression in (a) to find the position as a function of time. (hint: dr = v) (c) comment on this solution.

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

i think the answer is a, hope this is right, that would be my best guess.

seeing the graph would
