Question

starting from rest a car is moving unoform accelertion imagine what, happens to the displacement covered if time of travel is doubeled please answer this question in 2 minutes​

Answer 1

Answer:

Explanation:

u=0

a=a

in first case,, displacement => s = ut + 1/2 at^2

                                                    =0*t + 1/2 at^2

                                                     = 1/2 at^2

in second case,, displacement => s = ut + 1/2 at^2

                                                          =0* 2t + 1/2 a (2t)^2

                                                            = 1/2 a * 4t^2

                                                          = 2at ^2
