Question

Study the graph and answer the following questions
I) what type of motion is represented by OA ? II) what type of motion represent by BC?
III) calculate the acceleration produced from A to B
IV) Calculate the distance travelled in 20
V) find the average speed during 20 secs​

Answer 1

Answer:

answer are as follows

1 acceleration

2 retardation

3 no acceleration because there is no slope

so the vehicle is moving in constant speed

4 distance travelled in 20 sec is area under the graph

so distance travelled is

area of both triangle(1/2 into base into

height) + area of rectangle

= 24 +132+30

= 186 meter
