    Maximum velocity at the lowest point

    hi friend Assume that height of the hill is 'h' m. now initially as the car is rest on the top of the hill...KE is zero and PE is 'mgh' when the car is at the bottom of the hill the total PE at the top should be KE at the bottom...since PE at the bottom is zero At any point in...
