How do you do this? A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see figure below). The beam is uniform, weighs 200 N, and is 6.00 m long, and it is supported by a wire at an angle of ? = 60.0°. The basket weighs 80.0 N. a) When the bear is at x = 1.00 m, find the tension (in N) in the wire supporting the beam and the components of the force exerted by the wall on the left end of the beam. b) If the wire can withstand a maximum tension of 875 N, what is the maximum distance (in m) the bear can walk before the wire breaks?

Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures. F (N) Students collect data, see graph, for the force involved in stretching a rubber band. The data is well fit by the equation F = 33.65 x0.4971, 12 10 where F is in newtons and x is in meters. One end of the rubber band is attached to a stationary vertical rod and the other end to a 0.3 kg mass. The mass rests on a frictionless horizontal surface. The mass is pulled back such that the rubber band is stretched by 0.8 m from its unstretched length and then released from rest. 4. x (m) 0,1 0.02 0.04 0.06 0.08 A.

It is sometimes important to determine the location of a person’s center of gravity(which coincides with the center of mass because the gravitational force is uniform at the scale of the human body). This can be done with the arrangement shown intheFigure below. A light (negligible mass) plank rests on two scales that read Fg1=380 N and Fg2=320 N. The scales are separated by a distance of 2.00 m. How far from the woman’s feet is her center of gravity?
