A particle moves along a straight line so that after a time t (sec), its distance S(cm) from the starting point O is given by: S= t^3+15t^2+63t-40. Find: (a) the distance from O when the particle is momentarily at rest. (b) the velocity when the acceleration is zero.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

no
