Question

Anarcher shoots an arrow in the air horizontally? However after moving some distance the arrow move towards down name initial force that sets the arrow in motion explain why?

Answer 1

Initially, the archer exerts muscular energy on the string of the bow, and the string stores it as elastic potential energy. The string then releases this energy towards the arrow, which gains kinetic energy and moves horizontally. This arrow faces drag and gravity and eventually starts falling down.

Answer 2

Answer:

here both mechanical energy and potential energy is being conserved.

Explanation:

when the archer intends to pull the string of the arrow backwards it intends to create an energy enough strong to push the arrow in the forward direction in a projectile motion. when the string is released there, elastic energy is conserved where the arrows shoots itself forwards and after some time gravitational energy acts upon the arrow and later brings it to the ground. gravitational energy is not acting on the starts because the collision between the string and arrow is elastic and hence nullifying gravity effect on the arrow.

Hope this helps.
