Question

Speed-time graph of a body is shown in fig and answer the following
questions
What type of motion is represented by OA AB BC?
b) Find the retardation of the body.
c) Find out distance travelled in first 4 sec.
d) Find out distance travelled from A to B
e) Find out total distance travelled by the body in 16 sec.​

Answer 1

Answer:

Explanation:

-1,12,36,66

Answer 2

Answer:

This is a s-tor v-t graph .

OA- Accelerating (non uniform)

AB- constant (uniform)

BC- Retardation (non uniform.)

Retardation part is BC.

Retardation =slope

=>6/6 = 1 m /s²

Distance is equal to area.

Area of triangle OAX (x is position of 4 )

1/2 ×4×6=12.
