1.) The height from the ground to point A is 10m, from ground to point B is 6m, and from ground to point E is 1m. If the ball weights 100 N. What is the change in energy of the ball from point x to point y?
a. 10,000 J
b. 100 J
c. 0 J
d. 1000 J
2.) The height from the ground to point A is 10m, from ground to point B is 6m, and from ground to point E is 1m. If the ball weights 100 N, and its speed doubles as it reaches point C, what is its speed at point C?
a. 0 m/s
b. 8.94 m/s
c. 4.47 m/s
d. 34.64 m/s
1. Not enough information to answer this question (what are the points x and y?).
2. Again, the location of point C is reqired.
