An Interacting System of Two Objects Has No External Force

question 51

Essay

An interacting system of two objects has no external force acting on the system. The first object has a mass 2.00 kg and is moving with a velocity (2.00 m/s) + (1.00 m/s) at time t = 0.00 s. The second object has a mass 3.00 kg and is moving with a velocity (-1.00 m/s) + (1.00 m/s) at time t = 0.00 s. The second object is moving with a velocity (2.00 m/s) + (-1.00 m/s) at time t = 1.00 s.
(a) What is the total momentum of the system at time t = 0.00 s?
(b) What is the velocity of the first object at t = 1.00 s?

Definitions:

Symmetric

A characteristic of shapes or patterns that are identical on both sides when divided by a central line or axis.

Skewed

A description of data in which the distribution is not symmetrical, but instead has a longer tail on one side of the peak or the other, indicating an asymmetry.

Median

The value separating the higher half from the lower half of a data sample, a population, or a probability distribution.

Test Performance

Evaluation of the effectiveness or efficiency of a test, often measured in terms of accuracy, speed, or comprehensiveness.
