An object of mass m is attached to a vertically oriented spring. The object is pulled a short distance below its equilibrium position and released from rest. Set the origin of the coordinate system at the equilibrium position of the object and choose upward as the positive direction. Assume air resistance is so small that it can be ignored. a. Beginning the instant the object is released, select the graph that best matches the position vs. time graph for the object.
b. Beginning the instant the object is released, select the graph that best matches the velocity vs. time graph for the object.
c. Beginning the instant the object is released, select the graph that best matches the acceleration vs. time graph for the object.

x = A cos w * t     is a good choice where w = angular frequency

a. When the object is released the displacement is a maximum and proceeds towards zero in a quarter of a cycle.

b. When the object is released the velocity is zero and proceeds towards its maximum value in a quarter of a cycle         v = -w A sin w t

c. When the object is released the acceleration is a maximum since the quantity F = -K x is a maximum and the acceleration goes to zero in 1/4 cycle.

a = -w^2 A cos w t

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
