Question

for as illustrated in the diagram a cart has an initial speed 10m/s at the top of a 15-m friction track what is the speed of the cart at the top of the hill ?the acceleration due to gravity is 9.8m/s^2

Answer 1

what is the friction on this friction track
you gave the speed at the top - why do you ask for it? If it is another hill, what is the height?

Answer 2

Moreover for the sake of us physicists, please spell physics.
