2 A rocket sled accelerates at a rate of 49.0 m/s to a speed of 196 m/s. Then the rockets turn off and a parachute is used to decelerate the sled at a rate of 196 m/s2. Its passenger has a mass of 75.0 kg. (a) Plot the position of the rocket sled as a function of time from when it starts to when it ends. (b) For the initial acceleration and (c) the deceleration, calculate (i) the distance traveled by the sled, (ii) the horizontal force on the self, and (iii) the physical form of the total force vector on the rider of the sled from her seat. (d) How far does the sled travel in total? (e) What is the average force on the sled over the entire motion
