P029 An archer shoots an arrow at a 71.0 m distant target; the bull's-eye of the target is at same height as the release height of the arrow. (a) At what angle in degrees must the arrow be released to hit the bell's-eye if its initial speed is 37.0 m/s? 16 (b) There is a large tree halfway between the archer and the target with an overhanging branch 4.60 m above the release height of the arrow. Will the arrow go over c branch? over under Reading

Explanation / Answer

range x = ucos(theta)*t

t = 2usin(tehta)/g

x = u^2sin(2theta)/g

sin(2theta) = xg/u^2 = 71*9.8/37^2 = 0.508

theta = 15.27 degrees

b) over
