Question

A body is moving with 3 m/s and its acceleration is 2 m/s2. Find the distance travelled in 3rd second​

Answer 1

Answer:

Distance travelled in 3rd second = 8 m.

Explanation :

Refer the attached picture.

Answer 2

the distance travelled in 3rd second​  is 8m .

Explanation:

 distance travelled in 3rd second​  =  ?

initial velocity (u) = 3m/s

acceleration (a)  =  $2m/s^{2}$

for distance travel in 3rd second = distance travel in 3 second  -  distance travel in 2 second  

distance travel in 3 second is = ut + 1/2$at^{2}$

                                               =    $3*3+1/2*2*$$3^{2}$

                                              =   9 + 9

                                              =  18m

distance travel in 2 second is = ut + 1/2$at^{2}$

                                                = 3*2 +1/2 *2* $^{2^{2}}$

                                                =   10m

now for distance travel in 3rd second = distance travel in 3 second  -  distance travel in 2 second  

                                                      =      18m -10m

                                                       =     8m

now for distance travel in 3rd second = 8m

acceleration :- the rate of change of velocity per unit time is called acceleration the SI unit of acceleration is meters per second square
