The calculations I've done are about the energy change ,but as role of mass get obviated in equation ,It is not possible to get the value of mass of model . mg*200=0.5m*v^2 g*200=0.5v^2 but it doesn't seems independent of mass as results of experiment showed(8models). post comment

doubt... i read this problem statement as model designing problem,but it seems impossible because:- 1)inclination is too high and for such high inclination coefficient of friction required is tan60 (nearly1.588),whereas plywood has coefficient of friction 0.15 to 0.20. 2)normal toy cars are...

I hav doubt wheather a mechanical automobile model can move down from a path having inclination 62 without slipping (height =2meter,car dimensions=10*10*10cm3). pls give comment wheather it is possible or not if yes:- 1)how 2)which material could hav coeffiecient of friction =1.588 over...
