Question

A car accelerates uniformly at the rate of 2m/s^-2 after starting from rest. find the distance travelled and velocity attained in 4 seconds

Answer 1

Please refer to the above photo for the used process

We used two equations of motion to get the answer.
The equations are:

V= u +at
And, 2as = v²-u²

Hope this will be helping you!

Answer 2

Answer:

Here, a = 2m/s^2

         t = 4s

          u = 0

           v = ?  

                                 first equation ~= v =u +at

                                                          =0 + 2 * 4

                                                            = 8 m/s

third  equation~=2as+u^2 = v^2

                           = 2*(2)s + 0 = (8)^2

                           = 4s =64

                           s = 64/4 = 16m

                     I hope this answer would help you...

Thank you ...
