Assignment:
Question 1. Radio engineers are erecting a communications tower that is 16.0 m high. During the installation they stabilize the tower with 32.0 m long cables running from the top of the tower to the ground. The anchors consist of concrete blocks to which the cables can be secured. Each block weighs 1590 N. If the coefficient of static friction between a block and the ground is 0.800, what is the maximum tension that can exist in a cable before that cable's anchor is in danger of moving?
Question 2. An airplane traveling at 529 km/hr needs to reverse its course. The pilot decides to accomplish this by banking the wings at an angle of theta = 41.0 degree.
a) Find the time needed to reverse course.
b) How heavy would a 56 kg passenger feel during the turn? In other words, what would be the magnitude of the total force exerted on the passenger by the airplane seat?
