A97 kg man holding a 0.365 kg ball stands on a frozen pond next to a wall. he throws the ball at the wall with a speed of 11.3 m/s (relative to the ground) and then catches the ball after it rebounds from the wall. how fast is he moving after he catches the ball? ignore the projectile motion of the ball, and assume that it loses no energy in its collision with the wall.

What is the role of lenses in microscopy?

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.
