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?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
