What can you say about the potential energy of the two sleds shown below A. Sled A has more potential energy. B. Sled B has more potential energy. C. The two sleds have the same potential energy. D. There is not enough information to know which sled has more potential energy.

B. Sled B has more potential energy.

Explanation:

Option B is correct because when you carry out the calculation, you will find out.

Below is the calculation:

Potential energy = mgh where m= mass of sled, g=gravitational force = and h= height.

Sled A Potential Energy = 100kg x x 50m = = 49kJ.

Sled B Potential Energy = 200kg x x 30m =   = 58.8kJ.

So, since Sled B gave us 58.8kJ, it has more potential energy than Sled A that has 49kJ.

being judged by your physical appearance, gender, age or race has been a problem for many people around the world. we all have experienced segregation or rejection at some moment in our life. i   am not the exception. i am an overweight latin girl, two characteristics that do not me very much in a bullying society. i am an excellent student, speak beside my native language – spanish, english and i am currently studying portuguese. once there was a job opening for an international company. i was the perfect candidate for the position. i fulfilled all the requirements to get the job. yes, because of my   curriculum i was called for an interview. the same day, other candidates were appointed too.   i simply said to myself: this is for you, no one else is as prepared as you are, besides, you are smart, honest, responsible and reliable.

i felt like if a train had run over me. i felt miserable. he didn´t even asked me a question nor check on my skills! a pretty face and a perfect body was just as perfect for the position.

when i got home i cried for a long time until my tears dried from my being, then i told myself:   you are who you are, no one can tell you that you are not good enough because of your physical appearance. your intelligence will last forever! bodies age, faces disappear, but you   will always be
