Question

A block is attached to a spring. It is sliding back and forth on a frictionless surface. The graph above represents the displacement of the block from equilibrium as a function of time.

Evaluate each of the following statements:
(True False Greater than Equal to Less than) The speed at point B is _____ the speed at point H.
(True False Greater than Equal to Less than) The amplitude of the motion is 30cm.
(True False Greater than Equal to Less than) The speed at point B is _____ the speed at point F.
(True False Greater than Equal to Less than) The speed at point I is at a maximum.

Explanation / Answer

The speed at point B is __less than___ the speed at point H.

The amplitude of the motion is 30cm. (False. Since the amplituder of motion is 15 cm)

The speed at point B is __greater___ the speed at point F.

The speed at point I is at a maximum. (True)
