The magnitude and direction of half of the given vector A is 1.25 m east.
The given parameters;
- <em>magnitude of vector A = 2.5 m east</em>
A vector can be described with both magnitude and direction. The magnitude of the vector is the scalar or numeric representation of the vector.
When the scalar representation has direction, we term the quantity a vector quantity.
The magnitude of half of the given vector is calculated as follows;
Thus, the magnitude and direction of half of the given vector A is 1.25 m east.

Answer:
96.5 km/h
Explanation:
The average velocity of the train is given by:
where
d is the displacement
t is the time taken
For this train, we have:
d = 55 km south (displacement is a vector, so we must also consider the direction)
Substituting into the equation, we find the average velocity:
Answer:
<em>If the amount of water in the glass is close to brimming, then the pitch will ring as high-toned. </em>

Answer:
P = m (v2 - v1) change in momentum
P = - m v1 if v2 is to be zero
F = P / t change in momentum equals applied force
F = m a = - m v1 / t
a = -v1 / t or a * t = -v1`
Any combination of a and t that is greater than v1 will bring the space station to a halt
If a is small then t must be large
Any applied force will eventually bring the ship to a halt and then begin the acceleration towards the starting point
