SUMMARY

The discussion focuses on calculating the average net force acting on a 61.0-kg diver who enters the water at a speed of 4.71 m/s and slows to 1.60 m/s over 1.70 seconds. The calculated average net force is 111.594 N, which is confirmed as correct by participants. The importance of significant figures in reporting the final answer is also emphasized, particularly for online homework submissions.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Basic knowledge of kinematics and speed calculations
  • Familiarity with significant figures in scientific calculations
  • Ability to perform basic arithmetic operations with units of force (Newtons)
NEXT STEPS
  • Study Newton's Second Law of Motion in detail
  • Learn about kinematic equations and their applications
  • Review the concept of significant figures in physics problems
  • Explore examples of force calculations in fluid dynamics
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone involved in solving problems related to forces and motion in a fluid environment.

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.
 
Yup.
If your doing this for online homework or grading, remember your sig figs.
