The momentum of an object is a measure of force that acts on the object for a given time

Using the assumed final velocity, the change in momentum is 40 kgm/s

<h3>How to calculate the change in momentum</h3>

The change in momentum of an object is calculated using:

\Delta p =m\Delta v

Where:

  • m represents the mass of the object
  • \Delta v represents the change in velocity of the object

From the question, the mass of the box is 2 kg, and the box starts from rest.

This means that, the initial velocity is 0 m/s

The final velocity is not given. So, we make use of the following assumed value for the final velocity

v = 20 m/s

The equation then becomes

\Delta p =m\Delta v

\Delta p = m(v - u)

Substitute known values

\Delta p = 2(20 - 0)

\Delta p = 40

Hence, the change in momentum is 40 kgm/s

Which powers are given to the president by this excerpt from the constitution.
CaHeK987 [17]

Answer:

A constitution is a collection of fundamental ideas or established precedents that serve as the legal foundation for a polity, organization, or other forms of institution and generally dictate how that entity is to be governed.

Explanation:

- The president has specific authority to sign or veto legislation, command the military forces, request the written opinion of their Cabinet, convene or adjourn Congress, award pardons and reprieves, and welcome ambassadors, according to the Constitution.

- The President has the power to veto legislation passed by Congress under the Constitution. This authority is one of the most powerful instruments the President has to prevent legislation from passing.

- The veto gives the President the power to “check” the legislature by evaluating legislation approved by Congress and prohibiting actions that he or she deems unconstitutional, unwise, or unjust.
