that we have a car which I'm just gonna draw the box that's accelerating from rest. And it's so its initial velocity is zero Ah, and its velocity at after 4.5 seconds is 95 kilometers per hour. Now I want to convert this kilometers per hour into meters per second. So the way I'm going to do that is some dimensional analysis kilometers, I'm gonna turn two meters, which is 1000 meters and one kilometer and then hours. I want one hour for H is Ah, 3600 seconds. And this would give me its check. Ages cancel uh, Kilometers, cancel on you get meters per second and this is actually approximately surrounded 26 point for war meters per second. And if I want to find this average acceleration and you Delta V over Delta T and Delta V is final velocity minus the initial velocity and l T is gonna be 0.5 minus zero. So this is around 26.4. Uh, but I'm gonna not round it until the end. So it's like something, uh, minus zero over 4.5 minutes equals 5.9 meters per second squared
