  • you would need to know the weight of the arrow then add that onto gravity. use newtons laws, they have some formulas.
  • The acceleration of gravity here on Earth is 9.81 m/s^2. Given a starting velocity of 100m/s, the it would take (100m/s)/(9.81 m/s^2) = 10.2s to reach 0m/s. The average velocity is 50 m/s. So, the maximum height will be 50 m/s x 10.2 s = 510 m.
