Problem 1 (25 points) A rocket sled starts from rest at point A and accelerations at a rate of a = 9x (ft/s²) to a speed at point B, VB = 88 (ft/s), along a launching track of length D. After leaving the launching track at point B, the rocket sled begins to decelerate at a rate of a = -0.2 t (ft/s²) until it comes to the rest at point C. Determine. a) The necessary length D of the launching track? b) The time required for the rocket sled to go from point B to point C where it stops? c) The necessary length of the track L from point B to point C? B
