Answer:
Step-by-step explanation: Velocity is the first derivative of position function, so:
Since in the second scene acceleration is zero, velocity must be constant, which means velocity in the second scene is the same as in the first scene, i.e.,
To determine position function, integrate it:
Now, the "initial condition" is that
<u>Position function in the second scene is </u><u />
Isolate the x. note the equal sign, what you do to one side, you do to the other.
Multiply 0.4 to both sides
x/0.4(0.4) = 0.6(0.4)
x = 0.6(0.4)
Simplify
x = 0.24
0.24 is your answer for x

Here is a general method that you can use to solve all of these:
radius = diameter/2
diameter = radius * 2
circumference = 3.14 * diameter
area = 3.14 * radius * radius
