A uniform horizontal beam 10 m long is attached by a frictionless pivot to a wall. A cable making an angle of 30o (to the beam) is attached to the beam 6 m from the pivot point, supports the beam, which has a mass of 100 kg. The breaking point of the cable is 4000 N. A man of mass 100 kg walks out along the beam. How far can he walk before the cable breaks?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
