An 12 kg object accelerating from 9 m/s to 14 m/s. What is the change in momentum of the object?

Change in momentum = 60kgm/s.

Explanation:

Given the following data;

Mass, m = 12kg

Initial velocity, u = 9m/s

Final velocity, v = 14m/s

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;

To find the change in momentum;

Mathematically, change in momentum is given by the formula

Substituting into the equation, we have;

Change in momentum = 60kgm/s.

the correct choice is a .
