A64.0-kg person jumps from rest off a 2.98-m-high tower straight down into the water. neglect air resistance. she comes to rest 1.14 m under the surface of the water. determine the magnitude of the average force that the water exerts on the diver. this force is nonconservative.

The solution to the problem is as follows:

person's speed when water is hit = V = √2gh = 7.65 m/s 

person's momentum when water is hit = 7.65m = 489.6 kgm/s 

avg speed under water = 7.65/2 = 3.825 m/s 

time to stop under water = 1.14/3.825 = 0.30 s 

Favg = change in momentum/time to stop = 489.6/0.30 ≈ 1632 N ANS

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
