peter please if you could just give me the formula. i need to answer this question by tommorow and if i don't i will fail. i will ask my teacher to explain it but i can't ask him now. please will you give me the formula

A=.5xMxV^2 i don't know if this is right. is this how i would put the formula together. or would it be A=MGH but how would you find velocity im sorry but I am confused the height at the start point

sorry those were from the data .09 was height and .057 was mass so how would you put the formula together. with what symbols would you use. would you use GxMxH-h from what you said. i don't know how to put it together. if you could explain what i would use then it would mean a lot even though...

so i will use kinetic energy formula= height and then solve for speed so it would be .5x.05796xV^2=.09

was it by gravity because it was at standstill then moved on a hill downwards

im sorry but i still don't understand what would you do to find the formula

yes we did this roller coaster car problem in my physics class and i need to fill out an experiment sheet and this is one of the questions but i don't understand how to answer it

Homework Statement use conservation of energy to derive a formula for the speed of a car in terms of energy it has at the start. you have to use energy and height as the two variables Homework Equations The Attempt at a Solution i think it is kenetic energy x mgh
