Aball rolls 6.0 meters as its speed changes from 15 meters per second to 10 meters per second. whaf is the average speed of the ball as it rolls the 10 meters?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

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.
