Answer:
about -1.26 m/s²
Explanation:
The acceleration can be found from the formula ...
a = (v2² -v1²)/(2d)
Here, we have the initial velocity v1=23 m/s, the final velocity v2=0, and teh distance d=210 m. Using the formula, we find the acceleration to be ...
a = (0 -23²)/2(210) ≈ -1.2595 . . . m/s²

Answer:
Fran's upstream time = 37.93 hrs
Fran's downstream time = 30.13 hrs
Explanation:
given data
speed in still water = 2.62 km/h
River flows = 0.3 km/h
Fran to swim upstream = 88 km
solution
we will apply here distance formula that is
distance = speed × time ...................1
put here value
so here
Fran's upstream speed = 2.62 km/h - 0.3 km/h = 2.32 km/h
Fran's downstream speed = 2.62 km/h + 0.3 km/h = 2.92 km/h
so
Fran's upstream time = = 37.93 hrs
Fran's downstream time = = 30.13 hrs
