Solve the all parts of given question:

Question: A 2.0-kg object is at rest at the top of an inclined plane that makes an angle of 30° with the horizontal and which has a rise of 0.40 m. The 2.0-kg object begins to slide down the inclined plane, and at the bottom has a kinetic energy of 60 J. Ignore friction and use g = 10 m/s2.

Part A: How much work is done by the object in sliding down the inclined plane?

Part B: What is the speed of the object in m/s as it reaches the bottom of the inclined plane?

Please show how you obtained the answer for above question.
