A particle starts from rest, accelerates at 2 m / s 2 for 10 s and then goes for constant speed for 30 s and then decelerates at 4 m / s 2 till it stops. What is the distance travelled by it
Text Solution
Verified by ExpertsThe correct answer is:
A
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 

After that due to retardation
it stops

Total distance travelled
