SUMMARY

The discussion focuses on solving a problem related to the angular movement of a flywheel in a prototype car engine, where the angular position θ is defined by the equation θ = (3.0 rad/s³)t³. Key calculations include determining the distance traveled by a particle on the rim, finding the angle θ at specific times (t1 = 3.0s and t2 = 6.0s), calculating the average angular velocity between these times, and assessing the instantaneous angular velocity at both time points. Participants emphasize the importance of attempting the problem before seeking help, highlighting a collaborative approach to problem-solving.

PREREQUISITES
  • Understanding of angular motion and kinematics

Hi I don't have idea about solving it, If anyone can give me a descriptive answer or solve it for me, it'll be appreciable


The flywheel of a prototype car engine is under test. The angular position θ of the flywheel is given by θ = (3.0rad/s3)t3 and the diameter of the flywheel is 36cm.

(a)Find the distance that a particle on the rim moves during that time interval.
(b) Find the angle θ, in radians and in degree, at times t1 = 3.0s and t2 = 6.0s.
(c) Find the average angular velocity, in rad/s and in rev/min, between t1 = 3s and t2 = 6s.
(d) Find the instantaneous angular velocity at time t1 = 3.0s and t2 = 6.0s.

Sunjava1, we don't do your homework for you here, we can only help you towards your own solutions. To that end, you must provide an attempt to solve the problem or at least a description of your attempt and where you've become stuck. That is why the posting software provides a template...
