A body is projected up a 40 degrees rough inclined plane. If the coefficient friction is 0.5, then find the retardation of block.
Asked by acv27joy | 20 May, 2018, 09:02: PM
Expert Answer
frictional force acting on the block in retardation
f = uN (N is normal force)
N = mgcosθ
f = umgcosθ
component of weight acts in backward direction
Fb = mgsinθ
total force in downward direction is F+f
FT = umgcosθ + mgsinθ
maT= mg(ucosθ+sinθ)
aT= g(ucosθ+sinθ)
