Abody moving in the positive x direction passes the origin at time t=0.between t=0 and t=1second, the body has a constant speed of 27 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

In the first second of movement, the body's position at time relative to the origin is

so that after the first second, it will have undergone a displacement of

For every time , its position is then given by

so that after seconds, it will have undergone a displacement of

so it ends up 39 m to the left of where it started (taking the right of the origin to be the positive direction).

which statement about this sum is true? −245+2.7
