Question

. Study the speed –time graph and answer the following questions : A)What type of motion is represented by OA ?
B) What type of motion is represented by BC ?
C) What is the acceleration during A to B.
D) Calculate the retardation ?​

Answer 1

Answer:

Given:

Time loops = 4, 10 and 16

To Find:

Motions represented in OA, AB and BC and the distance travelled from A to B.

Solution:

1. In the region OA - The velocity increases uniformly with time, thus it represents uniform acceleration.

2. In the region AB - The body moves with a constant speed, and hence moving with zero acceleration.

3. In the region BC - The velocity decreases uniformly with time, and represents a uniform retardation.

4. Acceleration of the body OA = 6-0/ 4-0

= 6/4 = 1.5m/s²

5. Retardation in the body = 6-0/16-0

= 6/16 = 1m/s²
