word problem?

In a study of worker efficiency at Wong Labs it was found that the number of components assembled per hour by the average worker (t) hours after starting work could be modeled by the formula: N(t) = -3t^3 + 23t^2 + 8t.

A) rewrite the formula by factoring the right hand side completely

B) use the factored version of the formula to find N(3)

Diff Eq spring problem?

A mass weighing 3 lb stretches a spring 3 in. If the mass is pushed upward, contracting the spring a distance of 1 inch, and then set in motion with a downward velocity of 2 ft/sec, find the position of the mass at any time t. Assume that there is no damping and the only force acting upwards is the spring's force (F = -k(Delta(x))). Delta(x) = change of position from equilibrium. Determine the frequency (W), period (T), amplitude (A) and phase of motion (P). The answer by the way is x = (sqrt(2) * .25)*sin(8*sqrt(2)*t) - (1/12*cos(8*sqrt(2)*t)) ft. Where W = 8*sqrt(2), T = sqrt(2)*(pi/4), A = sqrt(11/288) and P = pi - arctan(3/sqrt(2)). I just don't know how to get this. Thanks.
