We define acceleration as the rate of change of the velocity
Thus, if you have positive velocity and positive acceleration, your <u>speed increases.</u>
If you have positive velocity and negative acceleration, your speed decreases.
Now you get the idea, we will see that the correct option is graph 1.
We know that the car moves towards the right (let's define this as "the car has positive velocity") and we also know that te car is slowing down constantly (thus the acceleration needs to be negative and constant).
By looking at the graphs, the only one with these properties is graph 1.

Potential energy is defined as
here we have
mg = weight = 5 N
now for different heights we can say
U = mgh
so potential energy in all three shells will be different and increases with height
<span>An isotope is a form of a
chemical element whose atomic nucleus contains a specific number of neutrons in
addition to the number of protons that distinctively defines the element. The
nuclei of most atoms have neutrons as well as protons.</span>
Find the kinetic energy using the formula E = 1/2(mv^2) where m = 17kg, v=18m/s, h=27m. Once you have found the answer, plug the answer as E, m =17kg, v=?, and h=27m. Now solve for v. Good luck
