The 200g model rocket,Angular acceleration

Click For Summary
SUMMARY

The discussion focuses on calculating the angular acceleration of a 200g model rocket generating 4.0N of thrust while spinning at the end of a 100g rigid rod. The net torque (Tnet) is calculated as 1.70 N·m using the equation Tnet = F * d, where F is the thrust and d is the distance from the pivot. The angular acceleration is determined using the formula angular acc = Tnet / (M * R^2), resulting in an angular acceleration of 23.57 rad/s². The total moment of inertia includes both the rocket and the rod's contributions.

PREREQUISITES
  • Understanding of Newton's laws of motion

Homework Equations

The Attempt at a Solution


Tnet= F*d= 4.0sin45*0.6
=1.70N.m
angular acc=Tnet/MR^2 =1.70/0.2*(0.6)^2
=23.57 rad/s
