Q12

Solving for the range of values for which v is positive here is akin to solving quadratic inequalities, except that I do not draw the graph this time.

Also note that “for which the velocity is positive” is different from “for which the velocity is increasing”.

Q13 is more of a trigo question than a differentiation question.

This property that a = -s explains a lot of the oscillatory motions that we encounter in daily life and is often studied in physics at the University level.
