What is the minimum coeffecient of static friction μmin required between the ladder and the ground so that the ladder does not slip?

Work = force × a. work b. energy c. distance d. momentum

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
