Question

A block rests on a horizontal, frictionless table. It is attached to a spring and set into motion. The picture above shows snapshots of the block at 5 different labelled locations during the motion. The two extreme locations (Points C and E) represent the two extremes of the motion of the block. Point A represents the equilibrium position. Evaluate each statement below, Choosing: Positive, Zero, or Negative.

The kinetic energy of the block at location D is ____.
The potential energy of the spring at location A is ____.
The potential energy of the spring at location C is ____.
The kinetic energy of the block at location A is ____.
The kinetic energy of the block at location E is ____.

Explanation / Answer

taking right extreme of equilibrium point as positive

figure is not opened I dont know where the point D in the table if it is right from equlibrium D is positive , it is left from equilibrium D is negative

The potential energy of the spring at location A is zero becaus it is at equilbrium point

The potential energy of the spring at location C is postive

The kinetic energy of the block at location A is positive

The kinetic energy of the block at location E is zero because at extreme position speed of the block will be zero
