Problem
An arrow must hit a target that is on the same horizontal level, 25 m from the archer. The archer can draw the bow to give any launch speed up to a maximum of 18 m/s. State whether the target can be reached within this speed limit, and, if so, calculate the minimum launch speed required (in m/s). Use g=9.8m/s2 and express the speed to two significant figures.
