Answer: vf = 32 m/s
Explanation: Solution:
Use the formula for acceleration:
a = vf - vi / t
initial velocity vi = 0 since it is at rest.
derive to find vf:
vf = at + vi
= 8.0 m/s² ( 4.0 s ) + 0 m/s
= 32 m/s

Answer:
8.6 miles
Explanation:
In order to calculate the straight-line distance between the starting point and the ending point, we need to resolve each part of the displacement into two perpendicular directions, let's say horizontal (x) and vertical (y) directions.
In the first part, Erica moves for 5.2 miles 25∘ north of east. Resolving into the two directions:
In the second part, Erica moves 5.0 miles north, so the components are
So the components of the net displacement are
And the magnitude of the net displacement is
Answer:
Continental polar ( cp):
Explanation:
Cold and dry, originating from high latitudes, typically as air flowing out of the polar highs. This air mass often brings the rattleing cold, dry and clear weather on a perfect winter day and also dry and warm weather on a pleasant day in summer.
