Question

The graph shows the acceleration, velocity, and displacement of a marble attached to a metal spring that has been secured to a tabletop. The marble was pulled down to the floor and then released. Which is true about the marble's motion? Motion and forces A. When acceleration is at a minimum, displacement is also at a minimum. B. When acceleration is at a minimum, velocity is at a maximum. C. When velocity is zero, displacement is at a maximum. D. When velocity at a maximum, acceleration is also at a maximum.

Answer 1

D. When velocity at a maximum, acceleration is also at a maximum.

Acceleration is the rate of change of velocity so, it is directly proportional to it, hence, when it will increase velocity will also increase

Hope this helps!
