angle deviation

[scienziato]

~45. Olylnpic target archers shoot .urows at a bull's-e~l-'e 12 cm

acrQ<s from a distance of90.00 m. If the initial speed of the

arrow is 70.00 mis, what must be dIe elevation angle? If the

archer misaims the arrow by 0.03" in the vertical direction, will

it hit the hull's-eye' Ifthe archer misaims the arrow hy O.O:~o in

the horizontal direction, will it hit the bull's-eye? Assume that

the height ofthe bull's-eye above the ground is the same as the

initial arrow height of the bow and ignore air resistance.

 

How could i possibly find this deviation?
