A 6-kg block slides down a frictionless incline making an angle of 60° with the horizontal.

(a) List all the forces acting on the block, and find the work done by each force when the block slides 2 m (measured along the incline).

(b) What is the total work done on the block?

(c) What is the speed of the block after it has slid 1.5 m if it starts from rest?

(d) What is its speed after 1.5 m if it starts with an initial speed of 2 m/s?
