An archer using a simple bow exerts a force of 180 N to draw back the bowstring 0.50 m. (a) What is the average work done by the archer in preparing to launch her arrow? (Hint: Compute the average work as you would any average quantity: average work = [final work - initial work].) (b) If all the work is converted into the kinetic energy of the arrow upon its release, what is the arrow's speed as it leaves the bow? Assume the mass of the arrow is 0.021 kg and ignore any kinetic energy in the bow as it relaxes to its original shape. (c) If the arrow is shot straight up, what is the maximum height achieved by the arrow? Ignore any effects due to air resistance in making your assessment.Ā 

Consider a similar situation to the problem above. An arrow with a mass of 0.420 kg is traveling horizontally when it hits a 1.45 kg target placed on a horizontal surface. This time the arrow embeds itself in the target and the target slides across a horizontal surface with friction. The target travels a distance of 6.8 m before it comes to rest. If the coefficient of kinetic friction is 0.40, what was the speed of the arrow before it hit the target?

Suppose an arrow that weighs 38.0 g was shot horizontally and has aspeed of 25.8 m/s when it strikes a target which has a mass of0.500-kg. The arrow then completely passes through the target andwith a speed of 8.9 m/s.

(a) suppose the target is at rest when struck, what would the speedbe after the arrow exits?
m/s

(b) what is the amount of energy lost as heat in thisscenario?
