4. An archer fires an arrow from a bow. The arrow's mass is 0.082 kg, and an average force of 120 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 the kinematic equations from the first week of class to calculate the velocity at the end of the acceleration. Assume a constant acceleration that corresponds to the given average force. b) Use the work-energy theorem to calculate the velocity.
