Question

A train towe: from one station to another in two hours ome. Its speed-time
praph during the motion is shown in Fig.
(0)
Determine the maximum acceleration during the journey
(10)
Also calculate the distance covered during the time interval 0.75 hour to 1
hour.
Ans: () 120 kmh
61) 8.75 km​

Answer 1

Answer:

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

=

0.25

60−20

=160

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

×0.25×40)+(20×0.25)=10km
