An 18.0-gram arrow is shot from a compound bow. (mass = 18g)
It travels the 0.980 m length of the bow with an average force of 125 N. The arrow enters a foam target. Embedding itself 11.2 cm into the target. (s = 0.980m, F = 125N, target length = 11.2cm)
What is the average force on the arrow by the foam target? (Average Force on arrow by foam target)

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...
