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.

If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object. Find the law describing the total force acting on this object.
