Question

A body at rest is given and initial uniform acceleration of 8.0m/s2 for 30sec after which the acceleration is reduce to 5.0m/s2 for the next 20sec,the body maintain the speed attained for 60sec after which it is brought to rest in 20sec. Draw the velocity-time-graph of the motion using the information given above

Answer 1

draw the three line segments. Since it is a graph of the velocity, the slope of each segment is the acceleration.
