Answer: 1.274 N minimum force required to slide the book across the surface
Explanation:
Mass of the book = m = 0.2 kg
Normal force acting on the book,N = mg
Coefficient of friction =
= 0.65
Minimum force required to slide the book across the surface= F


1.274 N minimum force required to slide the book across the surface
Answer:

Explanation:
given,
rotational inertia, I = 474.0 kg·m²
decrease in angular velocity
ω₁ = 26.2 rad/s ω₂ = 0 rad/s
time = 204 s
torque = ?



α = 0.128 rad/s²



frictional torque acting by the flywheel is equal to 60.88 N.m
A. Is the correct answer.
