47. An archer pulls the bowstring back for a distance of 0.470 m before releasing the arrow. The bow and string act like a spring whose spring constant is 425 N/m. (a) What is the elastic potential energy of the drawn bow? (b) The arrow has a mass of 0.0300 kg. How fast is it traveling when it leaves the bow?

1) An archer fires an arrow from a bow. The arrow’s mass is 0.088 kg, and an average force of 110 N is exerted by the bowstring over a 0.78 m distance. Calculate the velocity of the arrow just after it is released by the bowstring by two methods: a) Calculate the arrow’s acceleration that is caused by the bowstring, and use kinematic equations to calculate the velocity at the end of the acceleration. Assume a constant acceleration that corresponds...

In the Hunger Games, Katniss shoots an arrow at an apple in a pig’s mouth using a longbow. After careful analysis of the scene, my daughter and I estimate she is standing 12 m away and 3.5 m below her target. A typical shot from a longbow reaches speeds of 55 m/s. a) At what angle above the horizontal must she fire the arrow? There are two solutions (what do they correspond to?) and which one would be the one...
