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:

Question

a)if the conversion is 100% efficient.

b)if the conversion is 77.0% efficient.

Answer 1

work = energy

a) 182 * .380 = 1/2 * .0220 * v^2

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