. A particle moves along a straight line according to s(t) = sin(πt) + 2t^3. a) Determine the acceleration at t = 4.

b) Is the particle moving towards or away from the origin at t = 1.6?

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
