Question

A particle is moves along x axis with speed 6m/s for the first half distance and the second half distance with a speed 3m/s . Find the average speed in the total journey ?​

Answer 1

Answer:4

Explanation:we know that,

when an objects travels in two equal intervals then, the average velocity is:

2V1V2/V1+V2

(here,as assuming the path covered by a particle is in straight line then velocity=speed)

thus on putting the values in this formula,we will get:

2*6*3/6+3  =  36/9

= 4

so, the average speed of thye particle is 4m/s
