A 10 kg block experiences a frictional force of 8.66 N as it slides 2m down an incline as shown.
As
30
a) Draw a Free Body Diagram for the block and include As.
b) Find the coefficient of kinetic friction between the block and the incline
19) As the block moves 2m down the incline, find W, the work done on it by gravity,
d) As the block moves 2m down the incline, find Wr, the work done on it by friction.
le) Using Wnat = AK, find the block's kinetic energy, Ke when the block has moved 2m down the
incline, If its velocity at the top of the incline was 1 m/s.
1F) Now assume there was an additional force P on the block pointing up the incline.
Find W, the work done by P, so that the block moved down the incline with a constant speed.
