thanks guys but i figured out my problem. id use the formula pe=ke which is the equivalent of mgh * .5mv^2 so i can just simply eliminate the mass on the both sides and solve the equation

i can't know what the ratio is without finishing the arithmetic? or am i missing something

it reads, '' two identical objects move with speeds of 5m/s and 25m/s. what is the ratio of their kinetic energy so i think i need to use the equation ke=1/2 mv^2 this is how far i got ke=12.5*m and ke=312.5*m
