Question

8. Study the velocity time graph of an ascending passenger lift in the figure (a)What is the
acceleration of the lift during the first 2 seconds. (b)During the last two seconds. (c) Which
physical quantity is measured by the area under the quadrilateral ABCD? Calculate it






please help its urgent​

Answer 1

Answer:

In velocity time graph , time is taken on the X axis and velocity on the Y axis.

The area enclosed between the velocity time graph gives displacement of body.

Displacement = velocity x time.

Area of quadrilateral ABCD:

As it is a rectangle, we have area as :

Area = lxb

= 8x4.6

=36.8m

Therefore displacement under area ABCD IS 36.8m
