Use the values from PRACTICE IT to help you work this exercise. Suppose the same two vehicles are both traveling eastward, the compact car leading the pickup truck. The driver of the compact car slams on the brakes suddenly, slowing the vehicle to 5.78 m/s. If the pickup truck traveling at 17.4 m/s crashes into the compact car, find the following.

(a) the speed of the system right after the collision, assuming the two vehicles become entangled
m/s

(b) the change in velocity for both vehicles

Δv_truck	= m/s
Δv_car	= m/s

(c) the change in kinetic energy of the system, from the instant before impact (when the compact car is traveling at 5.78 m/s) to the instant right after the collision
ΔKE = J

For practice using exceptions, this exercise will use a try/catch block to validate integer input from a user. Write a brief program to test the user input. Use a try/catch block, request user entry of an integer, use Scanner to read the input, throw an InputMismatchException if the input is not valid, and display "This is an invalid entry, please enter an integer" when an exception is thrown. InputMismatchException is one of the existing Java exceptions thrown by the Scanner...

a. If you have two chromatograms of the same mixture, but they are from two different GC instruments, then how do you determine which one gives you better separation. For example, if the first one gives short, broad peaks and the 2nd one gives tall, sharp peaks then which instrument gives you better separation? Explain your answer. b. What is the retention time of peaks in the Gas Chromatograph tell you about the compound? For example, if you have a...
