1. The problem statement, all variables and given/known data Hey guys, a gravity car is driven by a weight connected to a string which in turn is connected to the axle, which the weight drives when dropped. I believe the solution is very simple, however I just cannot grasp it. My task is to calculate the distance of a gravity car given the weight of 840g (plus the falling weight, x) and the distance it falls. Initial velocity is 0m/s.The distance will be with respect to x, being the falling weight powering the car. Mass of car = 840g Mass of weight = x Distance Weight Falls = 250mm Distance = ??? 2. The attempt at a solution Well, the work that the falling weight will do is =mgh =.250*9.81*x = 2.4525x The mass of the car =.840+x Friction =u*Fn =.01*840+x*9.81 Distance =??? Thanks guys.
