InterviewSolution

1.	A car travels with a constant velocity of 15m/s for 4 seconds and then decelerates to come to halt in 4 seconds. Find the total displacement undergone by the car. Draw the v-t graph for the motion of this body.
Answer» time of DECELERATE = 4 seconds Decelerate =INITIAL VELOCITY = uFinal Velocity = vTime = tSince,Suppose , car STARTED from rest★ FINAL Velocity = 15m/s★ Time taken = 4 secondsDisplacement = - 30m/s
