Katniss pulls back a bow a distance of 0.51 m with a force of 215 N and lets it fly. What is the spring constant of the bow? ANSWER 1433.33
If kinetic energy is equal to Elastic Potential energy in the bow, what is the velocity of the arrow after it leaves the bow? (Assume the arrow has a mass of .033 kg) You have to use the spring constant k you calculated in the previous problem. ANSWER 210.48
If she fired it straight (not up or down at an angle) from a shoulder height of 1.4 m, how long would it stay in the air? ANSWER 0.53
Using the time the arrow was in the air and the horizontal velocity you computed above, how far did the arrow travel before striking the ground?
E) The time the arrow is in the air depends on its horizontal velocity? True or False.
F) Using the time the arrow was in the air and the horizontal velocity you computed above, how far did the arrow travel before striking the ground?
