People routinely use the phrases "no force", "zero force", "no net force", "zero net force" interchangeably so those are, within the... -

No! This the lesson of 1st Law. Being at rest or moving in a straight line at a steady speed are indistinguishable. One appears... -

Agree.
I agree with your numbers. -
inuka00123 replied to the thread Angular motion of a car wheel traveling at certain speed.I tried different equations, every one seems give a = 8.8 rad/s² and for displacement 330 radians, because I tried to plug the answer to...

This post shows that you are confused. You are given an initial angular speed of 7 revolutions per second. This means that if this...

Either way you will get the same answer if you do it right. Using the average angular velocity as @jbriggs444 suggested is more...

inuka00123 replied to the thread Angular motion of a car wheel traveling at certain speed.I am really confused, if I find the acceleration using ω₁ = ω₀ + at equation and plug that onto another equation or I can just use...

inuka00123 replied to the thread Angular motion of a car wheel traveling at certain speed.is it wrong to just use the θ = revolutions per second x 2π, after plugging the equations, θ₁ = rev x 2π = 7 x 2π = 44...

inuka00123 replied to the thread Angular motion of a car wheel traveling at certain speed.yeah, I saw that it means I need to multiply it by 2pi to get to the radians, can you give me the answer for this question, it would...

inuka00123 posted the thread Angular motion of a car wheel traveling at certain speed in Introductory Physics Homework Help.I assumed first the car is travelling 7 rad/s then accelerated to 14 rad/s in 5 seconds, after plugging the variables, I got θ = 35, I...

Most calculators will label it as "tan-1" rather than "arctan". In mathematics we generally measure angles in radians rather than...

You should be careful. That equation should be more clearly written as ##\tan(\alpha) = X/Y##. ##\tan(\alpha)## is the tangent function...
