Question 25 of 30 > A tightrope walker is walking between two buildings holding a pole with length L = 16.0 m, and mass mp-20.0 kg. The daredevil grips the pole with each hand a distance d = 0.500 m from the center of the pole. A bird of mass m 575 g lands on the very end of the left-hand side of the pole Assuming the daredevil applies upward forces with the left and right hands in a direction...

QUESTION 7 A box is at rest on a horizontal, frictionless table. Horizontal force F1 points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 6.75 m/s. Force F3 is also horizontal; it has magnitude 2.85F, and acts at an angle 22.6° to the direction of F1. If forces F1 and F3 act on the box at the same time, find the magnitude...
