Question
An archer fires an arrow, by applying an average force of 182 N across a distance of 38.0 cm on the bow. If the arrow has a mass of 22.0 g, find its velocity when the archer releases the bow:
a)if the conversion is 100% efficient.
b)if the conversion is 77.0% efficient.
a)if the conversion is 100% efficient.
b)if the conversion is 77.0% efficient.

work = energy
a) 182 * .380 = 1/2 * .0220 * v^2
b) .770 * 182 * .380 = 1/2 * .0220 * v^2
a) 182 * .380 = 1/2 * .0220 * v^2
b) .770 * 182 * .380 = 1/2 * .0220 * v^2
