Acceleration of the Sphere in the Inertial Frame:
In order to find the acceleration of the sphere in the inertial frame, we need to consider the forces acting on the sphere and apply Newton's laws of motion.
1. Forces Acting on the Sphere:
a) Gravity:
The force of gravity acts vertically downward on the sphere with a magnitude of mg, where m is the mass of the sphere.
b) Normal Force:
The normal force acts perpendicular to the surface of the floor and prevents the sphere from sinking into the floor. It has an equal magnitude and opposite direction to the gravitational force, i.e., mg.
c) Friction:
Since the sphere is rolling without slipping, the static friction force acts between the sphere and the floor. It provides the necessary torque to cause the sphere to roll. The maximum static friction force can be calculated using the equation f_friction = μ_s * N, where μ_s is the coefficient of static friction and N is the normal force.
2. Applying Newton's Laws of Motion:
a) In the x-direction:
The net force acting on the sphere in the x-direction is the horizontal component of the static friction force. This force causes the sphere to accelerate in the x-direction.
b) In the y-direction:
The net force acting on the sphere in the y-direction is the difference between the gravitational force and the vertical component of the static friction force. Since the sphere is not accelerating vertically, this net force is zero.
3. Equations of Motion:
a) In the x-direction:
Using Newton's second law, we can write the equation as:
ma = f_friction
ma = μ_s * N
b) In the y-direction:
Since the net force in the y-direction is zero, we have:
mg - f_friction = 0
mg = μ_s * N
4. Solving for Acceleration:
Dividing the equation in the x-direction by the equation in the y-direction, we get:
a/g = μ_s * N / mg
a/g = μ_s
Given that the coefficient of static friction, μ_s, is 0.71, we can substitute it into the equation:
a/g = 0.71
Therefore, the acceleration of the sphere in the inertial frame is 0.71 times the acceleration due to gravity (g).

a/g = μ_s * N / mg
a/g = μ_s

a/g = 0.71
Therefore, the acceleration of the sphere in the inertial frame is 0.71 times the acceleration due to gravity (g).
