Question

2. In the following velocity-time graph calculate the displacement covered by the object in
ta) First 20 seconds.
(b) In between 20 seconds to 30 seconds.
c) In between 40 seconds to 80 seconds.
11-14
1940
20
time in wee)​

Answer 1

Explanation:

we can find the displacement from velocity time graph by finding the area of the graph.

therefore,

• a) area of triangle=1/2×base×hieght

=1/2×20×20

=200m

• b)area of rectangle +area of triangle

=(length×breadth)+(1/2bh)

=(20×20)+(1/2×60×10)

=700m

• c)area of triangle =1/2×40×80

=1600m

hope this helps..!
