What is the molecular formula for xenon gas?

Simplify:

A train is traveling down a straight track at 20 m/s when the engineer applies the brakes, resulting in an acceleration of -1.0 m/s² as long as the train is in motion. How far does the train move during a 40-s time interval starting at the instant the brakes are applied?

How to graph ?

Using the Mean Value Theorem for Integrals. Find the value (s) of c guaranteed by the Mean Value Theorem for Integrals for the function over the given interval.
 

A 65.0-kg person throws a 0.0450-kg snowball forward with a ground speed of 30.0 m/s. A second person, with a mass of 60.0kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard friction between the skates and the ice. 

A bar magnet is held stationary while a circular loop of wire is moved toward the magnet at constant velocity at position A as in Figure CQ20.1. The loop passes over the magnet's center at position B and moves away from the magnet at position C. Viewing the loop from the left as indicated in the figure, find the direction of the induced current in the loop (a) at position A and (b) at position C. (c) What is the induced current in the loop at positon B? Indicate the direction as either CW (for clockwise) or CCW (for counterclockwise). 

Ammonia NH₃ chemically reacts with oxygen gas O₂ to produce nitric oxide NO and water H₂O. What mass of ammonia is consumed by the reaction of 4.94 g of oxygen gas?
