Homework Statement
When 100 joules of work is done upon a flywheel, it's angular speed increases from 60 rpm to 180 rpm. What is the moment of inertia?
Homework Equations
Angular Acceleration = (Radius)(Angular Velocity)^2
I= 1/2MR^2
Work=FD
The Attempt at a Solution
To be...
So,
Normal Force = 517 - (517x9.81)
Normal Force = 4554.77
Force of Friction = 183.194 - 285
Force of Friction = 101.806 N
Is this correct?
THANK YOU SO MUCH!
Net Force = Frictional Force + Weight Parallel
250 = Frictional Force + 226.576
23.424 = Frictional Force
Is this correct?
Once Again, THANKS FOR YOUR HELP AND QUICK RESPONE!
So,
NET FORCE
=250 N
VERTICAL
Y Component= (250)(sin 25)=105.654
HORIZONTAL
X Component= (250)(cos 25)=226.576
For problem 2, how do I finish finding friction?
