    How Does Physics Influence Soccer Ball Dynamics?

    anymore suggestions or thoughts? well is it necessary that I bring up translational/rotational kinetic energy, and linear and angular momentum or air resistance and ground resistance? I don't know how important these concepts are compared to what I am going to talk about in my paper. We can't...

    Difficulty on some distance problems

    I think that posting answers along w/ the worked out problems helps a lot more in understanding it thoroughly...but I guess if those are the rules that's cool...Thanks to both of you I was able to understand the problems more and get the final answers.. :)

    Difficulty on some distance problems

    You were given all the information called for by this equation except a, which you are supposed to solve for. I don't know what xf and xi are used for, which variables? You've got the right equation. The tension is equal to Fc. But why are you dividing by 3.14? As the equation says, you...

    How long to reach Mars at 11,000 m/s?

    11,000 m/s __________ 21,751,740 = 5.05 x 10^ -4 I got my numerator figure by converting 78.3 x 10 ^6 km and got 21,751,740 m/s

    How long to reach Mars at 11,000 m/s?

    A rocket moves through space at 11,000 m/s. At this rate, how much time will be required to go to Mars (78.3 x 10^6 km)? i used t= d/v and got 5.05 x 10^ -4 I'm not sure what I'm doing wrong. I can't get the correct answer
