A block of mass m = 1 kg is found on an inclined plane that makes an angle 30 with the horizontal The cocftficient of static friction and coef- ficieut of kinetic friction between the block and the ineline are: . = 0.6 and pa = 0.5. Take the positive di- rection to be up the inclined plane 130 With the block initialy at rest, the acceleration of the block is a = -9.33 a = 0.66 O Option 4 O Option 2 a = 0 a = -0.66

Transcribed Image Text:A block of mass m = 1 kg is found
on an inclined plane that makes an
angle 30° with the horizontal. The
coctficient of static friction and coef-
ficient of kinetic frictiou between the
block and the incline are: . = 0.6
and = 0.5. Take the positive di-
rection to be up the inclined plane
30
With the block initially at rest, the acceleration of the block is
a = -9.33
a = 0.66
