An archer needs to hit a bull's-eye on target at eye level of 60 feet away is the archer fires the arrow from the eye level with a speed of 47 ft/s at an angle of 25 degrees above the horizontal, will the arrow hit the target

If the arrow covers a horizontal less than 60 feet, it will not hit the bull eye, but if it covers a horizontal distance of 60 feet it will hit the bull eye.

For a Projectile, the Range , R = U²Sin(2θ) / g

speed , U = 47 ft/s ,  g = 32.2 ft²/s,  θ = 25°

R =  U²Sin(2θ) / g

R =  47²Sin(2*25) / 32.2

R =  2209Sin(50) / 32.2 

R = 52.55

Hence range is 52.55 feet.

Since the range is less than the required 60 feet of the bull's eye, hence it will not hit the bull eye.

Efficiency is an action of doing something. for example when you take a test. good efficiency means you did well but bad effeciency or no effiency means you did bad.
