Which of shakina's statements regarding acceleration and velocity is false? "when the acceleration is negative, the velocity can
Mekhanik [1.2K]
Let's start by imagining a rock being thrown to the air.
Let's say that going up is the positive direction and so, going down is the negative.
The acceleration is pointing down (because of gravity) so it's always negative. While the rock is going up, it's velocity/speed is positive, but the acceleration is negative.
While the rock is going down, both acceleration and speed are negative.
This shows that the first statemente is true, but the second is false.
You can also think that if you define going DOWN as the POSITIVE direction, you can have both positive acceleration and speed, or positive acceleration and negative speed.

Here's a graph of a linear function. Write the
svp [43]

First you need to find the y-intercept, which is y = -1

Next is we need to find the slope of the line > you are going to have to do this by finding to clear point

The ones that I will be using are: (3, 1); (6, 3)   (You could take any points)

Now using the slope formula we could find m.

m = y2-y1 / x2-x1

(1 - 3) / (3 - 6) = m

-2 / -3 = m

m = 2/3

Using the linear function format: y = mx + b

Therefore the equation of the line is y = 2x/3 -1
