I figured it out! I had to normalize aTT and realized T=1, so then I just had to plug that value into the aN equation along with the other given value. Thanks for responding anyways!

Hi, I have this math problem where I need to find the scalar component of acceleration at a given time under certain conditions. Usually these problems aren't bad for me, but this one has left me scratching my head. Its giving me ||a|| = 4 and (aT)(T) = 5i +5j -k I have the formula aN =...

I feel really bad because you're taking the time to help me, but this method is just completely new to me. I've checked with some class mates, and my class wasn't taught this, so it wouldn't be accepted. I'm so sorry, but are you sure there's no other way to go about this problem?

If you could, that would be greatly appreciated. Why wouldn't my idea work though? Does the relationship between deceleration and the friction just not work that way?

I am not. Which I assume why I'm confused. On another note, I've been trying to think of a way to figure this problem out, and I think for the first part I'm trying to go with using T=Iα however I'm not sure what α is. I have a hunch though, that because its the only force making the object...

Alright so the Force becomes F=Mg ,but you've kind of confused me with "Consider an element radius r, width dr, length drθ" Is there another way to explain this part, I don't recall my Professor ever even mentioning the width being involved in anything, it was always the radius.

1. A solid disk of radius R and mass M is initially spinning clockwise with an angular velocity magnitude ω. It is placed against a flat, horizontal surface with a coefficient of kinetic friction of μ. Find the frictional torque magnitude on the disk, and how long it will take the disk to come...

Thank you so much for all your help!

Alright so solved for the x and y components to get two equations and I isolated v3 on one, and theta on the other. However, that would end up making everything WAY to complicated cause I'd have something like v_3 =...

Ooohhh. I had completely forgotten about breaking vectors into components. Just to make sure, that's when instead of ((M_i)(v_0)-(m_1)(v_1)-(m_2)(v_2))/(m_3)=v_3 I would have ((M_i)(v_0*cos)-(m_1)(v_1*cos)-(m_2)(v_2*cos))/(m_3)=v_3*cos and then for the vertical components it would be sin...

Homework Statement An object, initially traveling southeast with a speed of v_0, explodes into three separate pieces. A fragment of mass m_1 travels due south with a speed of v_1. Another fragment, with a mass of m_2 travels travels northeast at v_2. The last fragment has a mass of m_3, but...
