2. A particle is moving along a horizontal line. The position of the particle from the origin after t minutes of travel is measured to be s(t) = 21 – 2712 + 84t + 25 feet, where t2 0. (a) Find the acceleration of the particle at all instances when the particle changed direction. (b) Determine the intervals of time when the particle is speeding up.
