A particle starts from rest, accelerates at 2 m/s2 for 10s and then goes for constant speed for 30s and then decelerates at 2 m/s2 till it stops. What is the distance travelled by it
Velocity acquired by body in 10 sec
and distance travelled by it in 10 sec
then it moves with constant velocity (20 m/s) for 30 sec
After that due to retardation (4 m/s2) it stops
So total distance travelled is 750 m.
