Question

10. The velocity-time graph of a moving body is given
below in Fig. 2.43.
Find :
(i) the acceleration in parts AB, BC and CD.
(ii) displacement in each part AB, BC, CD, and
(iii) total displacement.​

Answer 1

The acceleration in the mentioned part are given below:

Acceleration in AB=slope of AB

=tan(∠BAD)=30÷4 m/s

2

=7.5 m/s

2

Acceleration in BC is zero

Acceleration in CD=slope of CD

=tan(∠CDA)=−(30÷2)m/s

2

=−15 m/s
