Answer:No actually its the other way around women were just made be smarter than men normally this is proved through science if you look it up it should be in black letters in small letters
Explanation:
Answer:
Kinetic energy is increased
Explanation:
The net force on the bookcase in the direction of its motion is
∑ F = 65 N - F[friction] = (41 kg) (0.12 m/s²)
so that friction has a magnitude of
F[friction] = 65 N - (41 kg) (0.12 m/s²) = 60.08 N
The net force on the bookcase perpendicular to the surface is
∑ F = F[normal] - (41 kg) g = 0
so that
F[normal] = (41 kg) g = 401.8 N
If µ is the coefficient of kinetic friction, then
F[friction] = µ F[normal]
so that
µ = F[friction] / F[normal] = (60.08 N) / (401.8 N) ≈ 0.15
