What is the approximate momentum of a car with a mass of 1.20 10 kg and a velocity of 30.0 km/h?

Given:

or,

                      =

                      =

As we know,

→

By substituting the values, we get

Thus the above answer is right

Momentum = 10.0083kgm/s

Explanation:

Given the following data;

Mass = 1.2010kg

Velocity = 30.0 kilometer per hour to meters per seconds = (30*1000)/60*60 = 8.3333m/s

To find the 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 = 1.2010 * 8.3333

Momentum = 10.0083kgm/s

it has to be b, about 97 percent.
