Resolving Forces question applied force and friction force

Click For Summary
SUMMARY

The discussion revolves around calculating the friction force acting on a barge being pulled by a horse with a force of 7900N at an angle of 18 degrees. The mass of the barge is 9500 kg, and it accelerates at 0.12 m/s². The user correctly resolves the applied force using the equation 7900 x sin(18) and applies Newton's second law, concluding that the friction force is 1301.23N. This calculation is confirmed as accurate based on the provided parameters.

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Basic trigonometry for resolving forces
  • Knowledge of force components and their calculations
  • Familiarity with units of force (Newtons) and mass (kilograms)
NEXT STEPS
  • Study the application of Newton's laws in real-world scenarios
  • Learn about vector resolution in physics
  • Explore friction force calculations in different contexts
  • Investigate the effects of angles on force components
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of force calculations in practical applications.

Homework Statement



In earlier days, horses pulled barges down canals in the manner show in the figure below. Suppose that
the horse pulls on the rope with a force of 7900N at an angle of 18 to the direction of motion of the
barge, which is headed straight along the canal. The mass of the barge is 9500 kg, and its acceleration
is 0.12m/s2. What are (a) the magnitude and (b) the direction of the force on the barge from the
water?

Homework Equations



Kindly see if my orientation to solving the question is correct. If not ? Correct me.

The Attempt at a Solution



I resolve the force i.e 7900xsin(18)

Then I use "Applied Force - Friction Force = Mass x Acceleration"

7900xsin(18)= Applied Force
Friction Force= I have to calculate
Mass= It is given
Acceleration= It is given in question ...

The answer (Friction Force) is 1301.23N

Is it correct ?
