A cart is driven by a large propeller or fan, which can accelerateor decelerate the cart. The cart starts out at the positionx = 0 m, with an initial velocity of +5.5 m/s and aconstant acceleration due to the fan. The direction to the right ispositive. The cart reaches a maximum position of x =+14.0 m,where it begins to travel in the negative direction. Find the acceleration of the cart.
