Question

Take two aluminum channels of different lengths ​

Answer 1

Answer:

Now as the balls roll down they will gain velocity and height of the balls above the floor will decrease, i.e. potential energy of the ball will be decrease and kinetic energy will increase as they roll down with velocity v as shown in figure

Now kinetic energy of the balls of mass m moving with velocity v will be

K.E. = � mv2
