An object of mass 2 kg is held at the top of a triangular wedge, and then released. the reference level for potential energy is at the base of the triangle. neglect friction and use g=10m/s^2. height of triangular wedge=3m width of triangular wedge=4m. what is the amount of work done by the gravitational force as the object comes to the bottom of the wedge? also, what is the speed of the object just before it reaches the bottom of the wedge?
