Calculating Water Resistance for a Rowboat with Known Forces

Click For Summary
SUMMARY

The discussion focuses on calculating the water resistance experienced by a 285 kg rowboat subjected to a forward force of 112 N while accelerating at 0.120 m/s². Utilizing Newton's Second Law, the net force acting on the boat can be determined by multiplying the mass by the acceleration. The calculated net force allows for the deduction of water resistance, confirming the relationship between applied force, acceleration, and resistance in fluid dynamics.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Basic knowledge of forces and acceleration
  • Familiarity with mass and weight concepts

Homework Statement


285 kg rowboat being pushed by a forward force of 112 N from the paddles. If its is accelerating at 0.120 m/s(squared) how much water resistance is it experiencing? (assume gravity and buoyancy cancel each other)

Given:
a = 0.120 m/s (2)
Forward force = 112 N
Mass = 285 kg



Homework Equations


unsure, just confused.


The Attempt at a Solution


Do not understand where to start.
 
Physics news on Phys.org
Start with Newton's Second Law. You know that the *net* force on the boat is equal to the mass times the acceleration. You know the acceleration. From this, you can figure out what the net force should be.
