Asimple 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 with upward acceleration a2 = 4.84 m/s2. finally, in scenario 3, unfortunately for the rider, the cable breaks and the elevator accelerates downward at a3 = 9.81 m/s2.
fn1=
fn2=
fn3=

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particleâs motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energyâmomentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
