- Two construction workers carry a 2.8 m long wooden beam on their shoulders. It is horizontal while they carry it. One worker is at the end of the beam and the other is standing 2.6 m away from the first worker. The beam has a mass of 190 kg. a. Do the workers exert the same amount of force on the beam? You can just use intuition on this one. No math is required.arrow_forwardIn exercise physiology studies, it is sometimes important to determine the location of a person’s center of mass. This determination can be done with the arrangement as shown. A light plank rests on two scales, which read Fg1 = 380 N and Fg2 = 320 N. A distance of 1.65 m separates the scales.

- Many aspects of a gymnast's motion can be modeled by representing the gymnast by four segments consisting of arms, torso (including the head), thighs, and lower legs, as in Figure P8.85. Figure P8.85b shows arrows of lengths reg locat- ing the center of gravity of each segment. Use the data below and the coordinate system shown in Figure P8.85b to locate the center of gravity of the gymnast shown in Figure P8.85a. Masses for the arms, thighs, and legs include both appendages.

If the radius of the ball is 3.7 cm, find the center of mass of the arm–ball system.arrow_forwardUnderstanding the details of timing and forces in motion can improve the performance of athletes, including dancers. Consider the forces involved in a ballet jump called a sauté demi plié. P9.84a shows the sequence of moves in the jump. The dancer starts upright, then quickly bends her knees, moving downward. After she reaches the bottom of this dip, she extends her legs, pushing herself upward. After this upward push, she leaves the ground, beginning a short period of time in the air. P9.84b is a slightly idealized graph of the net force on a 42 kg dancer executing this move. The sauté demi plié begins with a phase in which the net force on the dancer is negative. During this phase of the jump,A. The normal force of the floor on her is zero.B. The normal force of the floor on her is less than her weight but greater than zero.C. The normal force of the floor on her is equal to her weight.D. The normal force of the floor on her is greater than her weight.arrow_forward
