i get it ..thank u

can u set these two equations equal to each other, cancel acceleration and solve for Vi or am I making it more complicated

well for acceleration you would use a= (Vf-Vi)/t for initial speed would you use a=2(x-V1t)/t^2

sorry. it's two different problems

so is the original speed then the same as the initial speed
