we know that
The scalar magnitude of the velocity vector is the speed. The speed is equal to
in this problem we have
substitute in the formula
therefore
<u>the answer Part a) is</u>
the speed is equal to
<u>Part b) </u>Find the velocity
we know that
<u>Velocity </u>is a vector quantity; both magnitude and direction are needed to define it
in this problem we have
the magnitude is equal to the speed
therefore
<u>the answer Part b) is</u>
the velocity is
Part c)
we know that
the acceleration is equal to the formula
in this problem we have
substitute in the formula
therefore
<u>the answer Part c) is</u>
the acceleration is
This is an example of negative acceleration

Step-by-step explanation:
Answer:
-12x = y^2
Step-by-step explanation:
Notice that the vertex and the focus are both located on the horizontal line y = 0 (that is, on the x-axis).
Because the focus is to the left of the vertex, we know that the parabola opens left.
The distance between focus and vertex is 3 units.
We'll adapt this equation: 4px = y^2. Here p is -3:
4(-3)x = y^2, or
-12x = y^2
360/8 = 45.
