Question

Solve the question no. 3

Answer 1

make fbd
write x and y force equation
assume x acceleration to be a
the eqns are:
FcosФ - f = Ma
f = uN
N = Mg - FsinФ
f = u(Mg - FsinФ)
FcosФ - u(Mg - FsinФ) = Ma
a = F/M(cosФ - usinФ) - ug
option (A)

Answer 2

Option a will be right absolutely right answer
