Question

The velocity- time graph of a moving body is given below:

Find
The acceleration in parts AB, BC and CD
Displacement in each part AB, BC, CD and,
Total displacement​

Answer 1

Answer:

velocity time graph Kha h

Answer 2

Answer:

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
