Homework Answers
Force of spring is always negative .
From hook's law, F is directly proportional to negative of stretch or compress .
=) F = - Kx
Here K is spring constant or constant of proportionality.
Hence last option is correct.

A 250 g block is moving along the “x” axis and at some point a
force in the positive direction of the axis acts on it.
The graph shows the magnitude of the force versus the position
“x” of the particle. The curve is given by F=a/x^2, with a=9.0 N.m2
. Find the work done on the block by the force as the block moves
from x=1.0 m to x=3.0 m by:
a.) Estimating the work from the graph.
b.)...

A cycler is moving along a straight stretch of road after starting at/=0. The velocity of the cycle is given by the graph to the right. Assume that positive velocity represents when the cycle is moving away from its starting point and negative velocity represents when the cycle is moving toward its starting point. At what point in time was the cycle moving most rapidly? Explain your claim. At what point in time was the cycle at a maximum distance...
