A motor boat heads east at 16 m/s across a river that flows north at 9 m/s. what is the resultant velocity speed and directions of the boat?

What is the coefficient of kinetic friction μk between the block and the tabletop?

What does the law of conservation of mass state?

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.
