Mass sliding down Inclined Plane

Question

If a 950kN box is sliding down an inclined plane angled at 60° from the horizontal and the distance from the box to the bottom of the inclined plane is 30.0m, then:

a.) What is the final velocity of the box as it reaches the bottom of the plane?

b.) If the same inclined plane was moved to the moon, what will be the mass of the box on the moon provided the weight of the box is the same as on earth.

c.) What is the acceleration?

and d.) How long will it take for the box to reach the bottom of the inclined plane?
