A particle starts from rest, accelerates at 
for 10 s and then goes for constant speed
for 30 s and then decelerates at 
till it stops after next. What is the distance travelled by it?
Text Solution
Verified by ExpertsThe correct answer is:
A
Total distance, 
Velocity acquired by body in 10 s,
Distance travelled by it in 10 s,
After that it moves with constant velocity, i.e. 
for 30 s,
Then, due to retardation of 
, it stops.
