44. Neglect of air resistance justifies setting a= –g= –9.8 m/s2(where downis our –ydirection) for the duration of the fall. This is constant acceleration motion, and we may use Table 2-1 (with Δyreplacing Δx).(a) Using Eq. 2-16 and taking the negative root (since the final velocity is downward), we have22020 2(9.8 m/s )( 1700 m)183 m/svvgy=−−Δ =−−−.Its magnitude is therefore 183 m/s. (b) No, but it is hard to make a convincing case without more analysis. We estimate the
