Homework Answers
Since the velocity is constant the acceleration is zero
So net force = 0
Upward force = downward gravitational force = mg
= 8200 x 9.81 = 80442 N

1. An undersea research chamber is spherical with an external diameter of 5.60 m. The mass of the chamber, when occupied, is 68400 kg. It is anchored to the sea bottom by a cable. The density of sea water is 1025 kg/m3. Calculate the following: (express your answers using appropriate mks units.) (a) the buoyant force on the chamber (b) the tension in the cable 2. A green brass block is placed on top of a 0.17 kg yellow styrofoam...

A simple elevator ride can teach you quite a bit about the normal force as this rider below can (hopefully) tell you. There are three different scenarios given, detailing the rider\'s experience in an unnamed hotel. For each scenario, calculate the normal force, FN,1-3, acting on the rider if his mass is m = 76.6 kg and the acceleration due to gravity g = 9.81 m/s2. In scenario 1, the elevator has constant velocity. In scenario 2 the elevator is moving...
