A:
a. Lu was running in a straight line in the positive x- axis with a decreasing velocity. At time t=15 min he stops and then again starts running with increasing velocity but in opposite direction.
In the first half i.e. before 15 min Lu is slowing down and at the second half i.e. after 15 min Lu is speeding up
