Given:
mass of blocw= mkg
angle of inclination =
mg sin@ e
mg coso
mg
b) from the FBD of
the block -
Net for ce on the block
Should be 0 in the
normal direction of
the inclination
so, N= mg cos(Ø)
direction : down the inclined
Therefore, the magnitude
of the normal force is mg cos (Ø)
and direction is down the
inclination
c)
acceleration along Net focce along
the aciekreilion
the inclination
Mass
a smg Sin (0) =) a=gsn(@)
