Hi. You can't use d/t for a movement that has acceleration.do you want to find the velocity of the start of the movement ? you don't need that. From v=at+v0 , we know that : x = 1/2 (a)(t)^2 + (v0)(t) + x0 so just put these numbers : x = 125 , t = 5 and you'll have a = 10 m/s^s The reason you can't use d/t is that , the idea v = d/t is only for movements with no acceleration , which have a constant velocity.
