Potential Energy Curves and Equipotentials?

Question

The potential energy of a particle moving along the x axis show in the image (click on link below for image). When the particle is at x = 1.0 m it has 3.6 J of kinetic energy. a) What is the total mechanical energy of the system? b) What is the smallest value of x the particle can reach? c) What is the largest value of x the particle can reach?

Note:

A has values 0 m and 10.0 J
B has values 2.0 m and 2.0 J
C has values 3.0 m and 6.0 J
D has values 4.0 m and 5.0 J
E has values 5.0 m and 10.0 J

Thank you so much!

Answer 1

The drawing has a couple of problems.
1. it shows only potential energy. So what was the kinetic energy at x=0?
2. It is not drawn to scale.

Let's consider some theoretical foundation.
The total energy (Et) equal to the algebraic sum of potential energy ( Pe) and kinetic energy (Ke).
Et=Pe-Ke
(and Et= mgh - 0.5mV^2)

Let Ke=0 at x=0
then
(a) Et=Pe = 10.0 J oules (this is the maximum energy
(b) the smallest value of x according to our assumption is x=0
however if you meant energy
Pe=10.0 J and Ke=0
(c) the largest value of x is infinity.

Max energy is 10.0 joules.

Something wrong with these questions

Answer 2

The stress is discovered from the capacity capacity from; F = - dU/dr you come across the equilibrium separation by fixing F = 0 for "r". (in words of A & B) next take the differential of the stress; dF = (dF/dr)dr evaluate (dF/dr) on the equilibrium "r" discovered above. Then if dF is constructive for constructive dr you are able to finish the stress is repulsive because the separation will advance previous the equilbrium separation. If dF is adverse then the stress is eye-catching. Then if dF is constructive for adverse dr you finish the stress is repulsive because the separation decreases from the equilibrium separation. If dF is adverse then the stress is eye-catching. you are able to do the records, which look lengthy.

Having other people do your homework for you is going to hurt you when finals come around.
