A cat of mass 1 kg runs at a speed of 2.5 m/s. What is the momentum of the cat?
A. 0.4 kg•m/s
OB. 1.0 kg•m/s
C. 5.0 kg•m/s
D. 2.5 kg•m/s

D. 2.5 kg•m/s

Explanation:

Given the following data;

Mass = 1kg

Velocity = 2.5m/s

To find momentum;

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;

Momentum = 1 * 2.5

Momentum = 2.5kgm/s

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

we need to know the time interval during which the force acts. impulse of force = momentum change
