Question

velocity of a body is moving with uniform acceleration of 3 metre per second square is changed through 30 metre per second the certain time average velocity of a body during this time is 30 metre per second distance covered by it is during that is ?
​

Answer 1

Answer:

300 m

Explanation:

Given Velocity of a body moving with uniform acceleration of 3 m/s^2 is changed through 30 m/s in certain time. Average velocity of body during this time is 30 m/s. Distance covered by it during this time is  

Given a = 3 m / s^2

We know that  

Acceleration = change in velocity / time.

a = v – u / t

      3 = 30 – 0 / t

      3t = 30

       t = 30/3

     t = 10 secs

we know that  

displacement = average velocity x time

   D = 30 x 10

       = 300 m

so distance covered will be 300 m

Answer 2

hey mate your answer is 300 m
