Let’s try a word problem!
Johneal pulled a 100 gram weight using a spring scale up
the smooth side of a chalk board. The spring scale read 80
grams as she pulled it evenly 25 centimeters. How much
work did Johneal do?

Brandon is traveling in his bike at 3 m/s. He then speeds up
Going down hill and at the bottom of the hill he is traveling
7 m/s. 8 seconds was the time he took to bike down the hill.
What is his acceleration rate?
