Calculation of the Mass of the Billiard Ball

To determine the mass of the billiard ball, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula for Newton's second law is:

F = ma

Where: - F is the net force acting on the object, - m is the mass of the object, and - a is the acceleration of the object.

In this case, the billiard ball is under the influence of two perpendicular forces, one with a magnitude of 0.8 H and the other with a magnitude of 0.6 N. The ball experiences an acceleration of 5 m/s^2.

To find the mass of the billiard ball, we can rearrange the formula as follows:

m = F / a

Substituting the given values:

m = (0.8 H + 0.6 N) / 5 m/s^2

Now, let's calculate the mass of the billiard ball using the given values.

m = (0.8 H + 0.6 N) / 5 m/s^2

Using the conversion factor, we can convert the force in hectonewtons (H) to newtons (N):

1 H = 100 N

m = (0.8 H + 0.6 N) / 5 m/s^2

m = (0.8 * 100 N + 0.6 N) / 5 m/s^2

m = (80 N + 0.6 N) / 5 m/s^2

m = 80.6 N / 5 m/s^2

m = 16.12 kg

Therefore, the mass of the billiard ball is approximately 16.12 kg.

Please note that the given values in the question are not standard units of force. The conversion from hectonewtons (H) to newtons (N) was necessary to perform the calculation.
