A student walks to class at the velocity of 3m/S. To avoid walking into a door as it opens, the student slows to a velocity of 0.5 m/S now late for class the student runs down the corridor at the velocity of 7m/S at what point in this scenario does the student have the least momentum?

Scenario 2

Explanation:

The momentum of an object is a vector quantity given by:

where

m is the mass of the object

v is the velocity of the object

From the equation, we see that the momentum is directly proportional to the velocity of the object.

In this problem, the velocities of the student in the 3 situations are:

v1 = 3 m/s

v2 = 0.5 m/s

v3 = 7 m/s

And since momentum is directly proportional to the momentum, the student has least momentum when he has least velocity: therefore, in situation 2.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
