4 A body moving in the positive x direction passes the origin at time t=0. Between t=0 and t=1 second, the body has a constant speed of 24 meters per second. At t=1 second, the body is given a constant acceleration of 6 meters per second squared in the negative x direction. The position x of the body at t=11 seconds is
