Problem 2 experiment produced data whose curve-fit particle acceleration was approximated by the equation a = 30 –- 3t², where a and t are expressed in ft/s and seconds, respectively. The particle starts at t = 0 with v = 0 and x = 12 ft. (a) the time when the velocity is again zero, (b) the position and velocity when t = 6 s (c) the total distance traveled by the particle from t = 0 to t = 6 s. Determine:
