When a body accelerates by at, what is the velocity after time ‘t', when it starts from rest?

You can create waves in any pond by throughing any stone then source of energy of waves.

A particle is in linear simple harmonic motion between two points, A and B, 10cm apart. Take the direction from A to B as the positive direction and give the signs of velocity, acceleration and force on the particle when it is:

At 4cm away from B going towards A.
