A billiard ball rolling across a table at [v1] m/s makes a head-on elastic collision with an identical ball.Find the speed of the second ball after the collision when the second ball is initially at rest. Express your answer in m/s.

A m = [m]-g bullet traveling horizontally with a speed of [v]×103 m/s enters an M=[M]-kg door, embedding itself [d] cm from the side opposite the hinges as in the figure. The [w]-m-wide door is free to swing on its hinges. Find the kinetic of the door-bullet system after the bullet is embedded in the door. 1 g = 10-3 kg, 1 cm = 10-2 m. The door’s moment of inertia in this problem is , where M is the door’s mass and L is the door’s width. Express your answer in J.

n=[n] moles of an argon gas are at a temperature of [T] K. Calculate the root-mean-square (rms) speed of an atom in the gas. The Boltzmann’s constant is kB = 1.38 ×10-23 J/K. The universal gas constant is R = 8.314 J/(mol.K). The argon’s molar mass is M = 39.95 g/mol = 39.95 ×10-3 kg/mol. Express your answer in m/s.

Suppose a wheel is initially rotating at 10.0 rad/s while undergoing constant angular acceleration reaching a speed of 30.0 rad/s after 24.0 seconds have elapsed. How long after the initial time has the wheel undergone half of the angular displacement that it will have gone through during the entire 24.0-second interval?
