Need some help with Phyics Final

A hungry bear weighing 660 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam (Fig. P12.42). The beam is uniform, weighs 200 N, and is 6.40 m long; the basket weighs 80.0 N.


Figure P12.42

   
    (b) When the bear is at x = 1.00 m, find the tension in the wire and the components of the force exerted by the wall on the left end of the beam.
    1 N (tension)
    2 N ( Fx)
    3 N ( Fy)
    (c) If the wire can withstand a maximum tension of 925 N, what is the maximum distance the bear can walk before the wire breaks?
    4 m

Do your own damn test.

a. the equation for the amount of time in your period in a circular orbit is [eqn]2pi*sqrt(a^3/u)

where a equals your altitude plus the radius of the earth and u equals the gravitational constant.

b. the formula for the velocity of a circular satellite is [eqn]sqrt(u/R)

where R equals the radius of your circular orbit
