Question

a train starts from rest and accelerates uniformly for 10 seconds and attains a velocity of 60 metre per seconds thereafter it travels with uniform velocity for 20 seconds then it uniformly decelerates for 12 seconds till it comes to rest. depict the motion of the train on a graph. plss help​

Answer 1

It is a velocity-time graph

The train starts from rest ie, 0 velocity

The train uniformly accelerates so use straight lines till time 10s and velocity 60 m/s

Then it travels with uniform velocity for 20s the line should be parallel to time axis .velocity as 60 till time 10+20=30s

Then it decelerates for 12s till rest

Line should be a straight line from initial velocity 60 to final velocity 0 and time 30+12=42s

Hope it helps.....
