Look at the triangle below.

a. what is the length of side a of this triangle?

b. what is the length of side b of this triangle?

a = 32.48538491

b = 25.59883264

Step-by-step explanation:

To find the length of a, use the sine function:

To find the length of b, use tangent:

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
