1. Calculate the portion of the force of gravity that is pushing the car down the ramp in the proper SI Units: F= M A2. Calculate the deceleration for the car from the end of the ramp to the cars stopping point: d= (1/2) a t^2 , for this calculation d = horizontal length the car travels from the edge of the ramp to stopping.3. Calculate the Potential Energy of the car at the top of the ramp: PE= mgd. For this calculation d is the height of the ramp.4. Calculate the velocity of the car at the end of the ramp just before it starts it's horizontal path to it's stopping point. PE=KE= (1/2) m v^25. Calculate the Work= F d done by gravity that pushes the car down the ramp. Which d(distance) do you use and why?Car weight is 36g.The steps aren't really clicking to me

Trial 1: Ramp height: Time stop Edge to stop: 20.5 in - 7 sec 3.52 see Length of ramp: Length from edge to stop. 48 in 240 in Trial 2 : Ramp height: Time stop: Edge to stop: 33 in . 58 sec 1-45 sec Length of ramp: Length from edge to stop 40 in 103.5 in
