Show that both pairs of opposite are parallel

Amachine, modeled as a simple spring-mass system, oscillates in simple harmonic motion. its acceleration is measured to have an amplitude of 5,000 mm/s with a fre- quency of 10 hz. compute the maximum displacement the machine undergoes during this oscillation.

What is the speed of an object at a given moment?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
