s

(b) How much time does she require to reach the opposite end if shewalks in the opposite direction?
s

Explanation / Answer

a) her speed is: v = 1.0m/s = 1.6m/s = 2.6m/s the time she takes t = d/v = 50.0m/2.6m/s = 19.23 s b) now her speed is v= 1.6m/s - 1.0m/s = 0.6m/s the time is t = d/v = 50.0m/0.6m/s = 83.33 s
