Calculating Net Force for a Diving Person | Homework Help

[Kris1120]

Homework Help! Please!

Can anyone tell me if I got this problem correct?

A 61.0-kg person, standing on a diving board, dives straight down into the water. Just before striking the water, her speed is 4.71 m/s. At a time of 1.70 s after entering the water, her speed is reduced to 1.60 m/s. What is the magnitude of the average net force that acts on her when she is in the water?

The answer I got is 111.594 N. Is that correct?

It looks ok to me.
