Consider a system consisting of two objects initially moving separately. The two objects collide and
stick together. If the objects continue moving after crashing, what can we state about the kinetic energy
and momentum of the system before and after the crash?
A. The kinetic energy of the system has decreased.
The momentum of the system has decreased.
B. The kinetic energy of the system remains constant.
The momentum of the system remains constant.
C. The kinetic energy of the system remains constant.
The momentum of the system has decreased.
D. The kinetic energy of the system has decreased.
The momentum of the system remains constant.

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

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.
