A 14 kilogram box slides down a long, frictionless incline of angle 30 degree. It starts from rest at time t = 0 at the top of the incline at a height of17 meter above ground.

(a) Find the original potential energy of the box relative to the ground?

(b) From Newton's laws, calculate the distance the box travels in 1 second and its speed at t = 1 second.
