text: can you answer this question about physic? one motor driver from calm state start to move and then after going 120m ,its speed reach to 30/0 m/s .indicate motordriver movement acceleration and the time he went this distance .(please write the way of solution) a=((v*v)-(v0*v0))/2x a=((30*30)-(0*0))/2*120 a=900/240 ===> a=3.75===> a=(v-v0)/t ===> 3.75=30/t ===>t= 30/3.75====>t= 8 secconds  this is so easy just use your brain
