Answer:
The speed of the object is ()m/s
The magnitude of the acceleration is 4.00m/s²
Explanation:
Given - position vector;
r = (2.0 + 3.00t)i + (3.0 - 2.00t²)j -------------------(i)
To get the speed vector (), take the first derivative of equation (i) with respect to time t as follows;
=
=
= ------------------------(ii)
To get the acceleration vector (), take the first derivative of the speed vector in equation(ii) as follows;
j
The magnitude of the acceleration |a| is therefore given by
|a| = |-4.00|
|a| = 4.00 m/s²
In conclusion;
the speed of the object is ()m/s
the magnitude of the acceleration is 4.00m/s²
Answer:
Social, physical behavior
Explanation:
The relational aggression is the aggression which caused or give to person by doing harm to his or her relationship or social image.
Reactive aggression is the aggression which is caused by threatening someone, or caused by provocation, or caused due to frustration.
Therefore, the basic differentiation in between both the aggression is that relational aggression is caused by by damaging social status whereas reactive aggression is caused through physical behavior.
