The equation of motion for a particle moving along the yaxis is given as y(t) = 21'2 8t + 3 for t 2 0. Part A: Find the velocity and acceleration functions. (10 points) Part B: Describe where the particle changes direction and the intervals where the particle speeds up or slows down. (20 points) f'(x) : cos(i2 + x), Let f(x) be dened such that f(1) = 2 and X where O
