    Calculate the centre of mass of the object shown below

    I have a few questions that are driving me nuts. First: Calculate the centre of mass of the object shown below. Assume that the mass density is uniform. Place the origin, O, at the lower left. If the positive x-axis points to the right along the page, what is the x coordinate of the centre of...

    Finding distance using vector components

    That is a helpful link, however I still can't get the answer. XD Do I have to find the angle between r1 and r2 and use that to find the distance or does it have to do with the addition of the i hat components and the j hat components?

    Finding distance using vector components

    Homework Statement With reference to Fig. 3 (not accurate), where the origin is at the centre of the image, if r1 = (0.10)î+(-0.80)j hat, and r2 = (-0.90)î+(0.10)j hat, what is the distance between the dots? Homework Equations Unsure. The Attempt at a Solution I'm not so good with these...
