    Graviational acceleration given mass and radius

    Thanks, I actually went back and redid it later and got the answer I was looking for.

    Graviational acceleration given mass and radius

    Homework Statement If you lived on a planet with five times the mass of Earth and twice the radius, what would be the gravitational acceleration at the surface of your planet? Homework Equations GM/r^2 Mass of Earth = 6.00*10^24 kg Radius of Earth = 6.38*10^3 km The Attempt at a...

    Elastic Collision Problem - pretty sure my answer isn't right.

    Then Wolfie's speed after the collision is higher than the velocity that Walt hit Wolfie with initially, which doesn't seem right.

    Elastic Collision Problem - pretty sure my answer isn't right.

    Homework Statement Walt and Wolfie collide in bumper cars of mass 50 kg each. Walt has a mass of 78 kg, and Wolfie has a mass of 61 kg. Walt strikes Wolfie from the rear at V = 3.7 m/s. If the collision is elastic, Wolfie is initially at rest, and Walt's final speed is 0.2655 m/s in the same...

    Chemistry Partial pressure and moles problem?

    Oh sorry... it was late. Must've have just typed NO instead of CO. lol Guess I get my oxides mixed up. There is an image attached, but I thought I had included it in my attempts. Sorry. There's 1L of O2 at 1atm and 2L of CO at 0.5atm. And that is all the information I'm given.

    Chemistry Partial pressure and moles problem?

    Homework Statement Here is the problem: Carbon monoxide and oxygen are kept at exactly 300 K in separate chambers of the apparatus shown below. When the stopcock is opened, the combustion reaction begins and is allowed to proceed to completion, while being maintained at exactly 300 K...

    How Accurately Can We Estimate Volume Error Using Tangent Line Approximation?

    I'm not sure how to work this into the entire problem though, especially in regards to TLA

    How Accurately Can We Estimate Volume Error Using Tangent Line Approximation?

    Homework Statement You measure a cubic container and find it to be about 10 cm on each side. From this, you conclude that it holds 1000 cc. However, your measurement is accurate only to within ±0.1 cm. (So you can be sure that the side is between 9.9 and 10.1 cm.) What are x, f(x) , and a in...
