1. The problem statement, all variables and given/known data[/b ]Here’s what you know: Mass is 750 Kg, Velocity is 20 m/s, Gravity remains at 10 m/s2 and Point B’s height is 15 m. Assume that Point A is the highest point and assume there is no friction for this problem. Complete in the order that makes the best sense to you: Calculate the total energy at Point A and Point B. Determine Point A’s height. 2. Relevant equations E= mgh + ½ mv2 3. The attempt at a solution Energy at Point B: (+ 4 pts) E= mgh + ½ mv2 E= (750) (10) (15) + 0 E= 112500 J I found the Ep for Point B. When I tried to work "backwards" by trying to find Point A's height by using Point B's Ep and height, I came up with a negative energy. I think there should be a way to use this known data to determine point A's height and Ep, but I can not figure it out.
