Step-by-step explanation:
It is given that,
Initial speed of the car, u = 40 m/s
Final speed of the car, v = 25 m/s
Time taken, t = 3.5 s
(a) We need to find the magnitude and direction of the car’s acceleration as it slows down. It can be calculated using formula as :
The acceleration is in the opposite direction of motion i.e. west.
(b) Let s is the distance the car travel in the 3.5-s time period. It can be calculated using the third equation of motion as


s = 113.9 meters
Hence, this is the required solution.
Answer:
9 + 10 +x= 21
x=21-19
x=2
add 2 in left hand side to get 21
For this case we have that by definition:
A triangle is defined by three lines that are called sides, or by three points called vertices.
We know that:
- <em>The vertices of a triangle are labeled with capital letters.
</em>
- <em>The sides of a triangle are written with lowercase letters.
</em>
- <em>The angles of a triangle are written similarly to the vertices.
</em>
Answer:
The end points of the triangle are called vertices.
They are labeled in capital letters.
The vertex of the parabola is <span><span>(<span>2,1</span>)</span><span>(<span>2,1</span>)</span></span>
.
So, the axis of symmetry is the line <span><span>x=2</span><span>x=2</span></span>
