a device has a 100g wooden shuttle that is pulled along a square woooden rail by an elastic band. the shuttle is released when the elastic band has 9.0 N tension at a 45 degree angle. what is the magnitude of the initial acceleration of the shuttle?

  • physics - ,

    F=ma

    What are the forces on the shuttle
    a> gravity
    b> rubber band. the force of gravity down the rail is mg*.707

    9-0.1*9.8*.707=0.1*a
    solve for a

    thanks, how did you get the .707 though?
