An object increased its velocity from rest at 60m/s in 20 seconds. Then, it continues to move with a constant
speed for the next 20 seconds and slowed to a stop within 30 seconds. After 10 seconds of rest, the object increased
its velocity again to 40m/s for 20 seconds and continued moving at that speed for the next 20 seconds. Plot the
velocity-time graph of the motion of the object.​

Answer:

Well I assume we are starting at rest and then increasing our velocity to 40m/sec.

Well the definition of acceleration or formula states that

A=velocity final-velocity initial/time

Acceleration =40–0/10

A=4m/s^2 that is the acceleration
