SUMMARY

The discussion focuses on calculating the tangential acceleration of a flywheel with a radius of 0.200 meters and a constant angular acceleration of 0.900 rad/s² after it has turned 60 degrees. The key formula used is atan = α * radius, where α is the angular acceleration. The participant confirmed that the tangential acceleration remains atan = 0.180 m/s², regardless of the distance turned, as the angular acceleration does not change during this phase of motion.

PREREQUISITES
  • Understanding of angular acceleration and its units (rad/s²)
  • Familiarity with the relationship between linear and angular motion
  • Knowledge of basic trigonometry, specifically the tangent function
  • Ability to perform unit conversions and calculations involving radians
NEXT STEPS
  • Study the relationship between angular displacement and angular acceleration in rotational dynamics
  • Learn about the concepts of centripetal and tangential acceleration in circular motion
  • Explore the effects of varying angular acceleration on tangential acceleration
  • Investigate practical applications of rotational motion in engineering and physics
USEFUL FOR

Students studying physics, particularly those focusing on rotational dynamics, as well as educators and professionals involved in mechanical engineering and related fields.

Homework Statement

A flywheel with a radius of 0.200 starts from rest and accelerates with a constant angular acceleration of 0.900 .

atan= .180 m/s2 when its at rest
arad= 0m/s2 when at rest
compute magnitude of resultant acceleration at the start a= .180 m/s2

I got all of these already now the question is

Compute the magnitude of the tangential acceleration of a point on its rim after it has turned through 60.0?

atan= ? m/s2

The attempt at a solution

I do not know how to answer this. I honeslty don't know where to start.

I know atan= [itex]\alpha[/itex]*radius but i don't know what to do now that the flywheel is turning 60

Solved it.

Turned out that i didnt need to worry about how far it moved so it was just Alpha*radius

Giving me atan=.180m/s^2
