what do you think?

sorry b.
Answered by bobpursley
b? Hmmmm. acceleration= force/mass, and that is equal to kx/mass

so acceration depends on x

then its d

Hmmmm. At the extreme positions, velocity is zero, it changes directions, the question asked which is not true. Are you guessing or thinking?

A then ... guessing i don't understand this stuff at all -_-
Answered by bobpursley
WEll, you missed it three out of three, and your first guess was right. The velocity is NOT zero at the equilbrium position, it is maximum there.
