Answer: I showed you all calculation . You did not attach any graph to question .
Explanation:
Lets first find Velocity
Vr=o m/s
Ve=?
a=1m/s²
t=2s
----------
a=(Vr-V)/t
1m/s²=Vr-0m/s/2s
2m/s=Vr
Lets find the time neeeded to stop :
a=1m/s²
Vs=2m/s
Vf=0m/s
a=(Vf-Vs)/t
t*1m/s²=2m/s
t=2 s
Going upstream against the current gives a net speed equivalent to the speed at still water minus the speed of the current. Consequently, the speed downstream gives a net speed equal to the speed at still water plus the speed of the current, making it travel faster. The solution is:
UPSTREAM
v = 20 - 1.5 = 18.5 km/h
t = 30 mins or 0.5 hours
distance = 18.5km/h (0.5 h) = 9.25 km
DOWNSTREAM
for the same distance of 9.25 km:
v = 20 + 1.5 = 21.5 km/h
t = 9.25km / 21.5 km/h = 0.43 hours or 25.8 mins = 26 mins --> FINAL ANS.
