please help me ? Starting from rest, a 5.00 kg block slides 1.50 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is μk 0.436. Determine:

B) the work done by the friction force between block and incline
C) the work done by the normal force

Hint #1: In future, post physics questions in the physics forum. 
Hint #2: Draw a free-body diagram. 
Hint #3: Work = Force in the direction of motion * Distance in the direction of motion. 

Good luck!
