i couducted an experiment trying to calculate the drag of a toy car going down a slope, i measured this at different distances 2.0m to 0.5m at 0.1m intervals along a 15 slope. i measured the time using light gates. i put one light gate at the end of the slope and one where the car started from e.g. 2.0m or 0.5m

how do i work out the drag?

results for 2m are 1.24s
i tried working out the actual average velocity and then the theoretical average velocity

i tried working out the actual veloity by using vectors and suvat
2cos15 = 1.93
2sin15 = 0.52
i worked out the vertical acceleration and also the horizontal acceleration

how do i work out the actual velocity and the theoretical velocity down the slope?
