A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.62 of the person's regular weight. Calculate the acceleration of the elevator, and find the direction of acceleration.
Arlene is to walk across a high wire strung horizontally between two buildings 14.0 m apart. The sag in the rope when she is at the midpoint is 10.0°, as shown in Figure 4-42. If her mass is 56.0 kg, what is the tension in the rope at this point?
Thanx
