[SOLVED] Conservation of Energy
I know, this problem is making me feel dumb but I can't figure it out:
A crossbow takes 50.0 pounds of force to draw the arrow back by 12.5 inches, and the weight of the arrow is 2 ounces. What is the speed of the arrow when it is released?
(1 lb = 4.448 N; 1 in = 2.54 cm; 1 oz = 28.35 grams)Could someone show me how to solve this?? Thanks to whoever helps.
*It is not momentum, but conservation of energy, sorry.
