Anew ride being built at an amusement park includes a vertical drop of 71.6 meters. starting from rest, the ride vertically drops that distance before the track curves forward. if friction is neglected, what would be the speed of the roller coaster at the bottom of the drop?

If y gets smaller as x gets bigger and y have an relationship?

Abowling ball rolling down the lane toward the pins has gravitational potential energy. a. no b. a lot of c. a little

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s 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 energy–momentum 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?
