Question

3)Study the speed- time graph of a body given here and answer the following questions:

i)Calculate the retardation of the body.

ii) Find out distance travelled by the body from A to B

Answer 1

Answer:

retardation=1 m/s^2

distance of AB=36 m

Explanation:

retardation=slope of BC=0-6/16-10=-6/6=-1=1 m/s^2

distance of AB=ar(ADEB)=6*6=36 m
