Discussion Question (20 points): Suppose you are traveling in a bus that has a mass of 125kg at a highway speed
of 45km/s for 10s on a nice summer day and the momentum, 250kg. m/s, of an
unlucky bug with a mass of .25kg is suddenly changed as it splatters onto the
front window.
This is NOT a multiple choice question! Answer all questions (1-4).
1. Compared to the force that acts on the bug, how much force acts on the bus?
(Find the speed of both the bus and bug. Remember: you need
acceleration!)

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
