Troubleshooting a Physics Calculation: Identifying the Problem

Click For Summary
SUMMARY

The discussion focuses on troubleshooting a physics calculation involving a mass M of 0.58 kg sliding inside a hoop with a radius of 1.50 m. The participant seeks to determine the force exerted by the mass on the hoop at an angle of 46.0°, using principles of energy conservation to find the velocity at that point. The calculations involve comparing the gravitational force component perpendicular to the hoop with the centripetal force required for circular motion. The participant expresses confusion over the results, indicating a potential misunderstanding of the problem's requirements.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with centripetal force calculations
  • Knowledge of energy conservation principles in physics
  • Ability to perform vector decomposition of forces
NEXT STEPS
  • Review the concept of centripetal force and its calculation
  • Study energy conservation in mechanical systems
  • Learn about vector decomposition in physics problems
  • Practice similar problems involving forces in circular motion
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in solving problems related to forces in circular motion.

hi,
could some one please explain where i am wrong?

A mass M of 5.80E-1 kg slides inside a hoop of radius R=1.50 m with negligible friction. When M is at the top, it has a speed of 4.43 m/s. Calculate the size of the force with which the M pushes on the hoop when M is at an angle of 46.0°.

i guess what i need to find is the difference between the perpendicular to the hoop component of mg and the centr. force. the centr. force needs the v in that point
which i can find using energy conservation.
i get the wrong answer. i think i am not wrong calculating. maybe what i am asked is not
what i end up calculating

thanks
