90 km/h = 90x5/18 = 25 m/s = initial velocity = you 55 km/h = 55 x 5/18 = 15.278 m/s = final velocity = v a = acceleration = - 4.5 m/s² v² = u² + 2as => 15.278² = 25² - 2(4.5)s => s = 391.59/9 ~= 43.51 m hope this helps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
