A ball is moving at 4.5 m/s and has a momentum of 75 kg·m/s. What is the ball's mass?

The ball's mass will be "16.67 kg".

Momentum seems to be the product of a subatomic particle mass as well as the velocity. Momentum would be vector quantity, which means it does have a magnitude as well as an orientation.

In contrast, a particle's momentum seems to be a measurement it takes for a continuous force to bring that one to remainder.

According to the question,

Velocity = 4.5 m/s

Momentum = 75 kg.m/s

By using the formula,

→ Momentum = Mass × Velocity

or,

→          

By substituting the values,

Thus the above answer is right.

Mass = 16.67kg

Explanation:

Given the following data;

Velocity = 4.5m/s

Momentum = 75kgm/s

To find the mass;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

Substituting into the equation, we have

75 = mass * 4.5

Mass = 75/4.5

Mass = 16.67kg

Therefore, the ball's mass is 16.67 kilograms.
