Question

a train moves from one station to another in 2 hours time its speed time graph during the.motion is shown in figure determine the maximum acceleration also calculate the distance coveredduring thrle time interval from 0.75 hours to 1 hours
​

Answer 1

Maximum acceleration will occur in the region with maximum slope.

From the given curve region CD is having the maximum curve.

Thus, maximum acceleration=

change in distance/change in velocity

60-20/0.25

=160

Now, total area under the curve between 0.75 to 1.00 hrs is given by

(1/2 ×0.25×40)+(20×0.25) =10k

Hope this helps you!!
