(1,1)? So it'll be from 0 to 1 correct? If we were to do it that way, the point of intersection would be 1 and I'm guessing the radius will be on top of the curve? So it'll be... SQRT(1-x^2) - (x^5)?

Homework Statement The area in the region inside the unit circle and above the graph of f(x) = x^5 Homework Equations I don't know how to type the equation in here but the area is the integral between two integration points of the higher curve minus the lower curve. The Attempt at a...

Nvm, I figured it out, just had some bad algebra.

Thanks for the reply, I just checked in my book and it also said to use the conservation of momentum equation. Solving for vf, I ended up with: vf = mvi/3m plugging it back into the energy equation still doesn't yield the result :(, unless I'm doing it wrong somewhere.

Homework Statement The two blocks I and II shown above have mass of m and 2m respectively. Block II as an ideal massless spring attached to one side. When block I is placed on the spring as shown in figure (a), the spring is compressed a distance D at equilibrium. Express your answer to all...

I must've misunderstood your question, I simply thought that because the mass is having a linear acceleration downward, therefore causing the pulley to have an angular acceleration, they must be the same :S. I'm bad at this angular stuff :(. Angular acceleration the change in angular velocity...

It's the same?

Homework Statement The goal is to solve for angular acceleration with the end variables being m1,m2,m3, R, r, g. M2 > M1. An atwood machine is a pulley with 2 masses, one on each side. Homework Equations Tnet = I * angular acceleration Fnet = ma The Attempt at a Solution I know...

Thank you! I understand now.

Ok, so I understand that when the cart is accelerating, the hanging mass is at rest and what you propose make sense. So for this case, is the Ft equals to the Fw since the object is at rest? And I don't get this fictive force thing =|. Btw, the answers are: a) 13 m/s/s to the right b) 8.3n...

A 50kg weight hangs from the ceiling of a cart that is accelerating horizontally. While the cart is accelerating, the weight swings to the left so that the string makes an angle of 37 degree with the horizontal ceiling. a) What is the size and direction of the acceleration of the cart? b) What...
