Solution for On-Line Homework 5 Inertia II Solution to On-Line Homework Problem 5.1(Smaller Inertia Means Easier to Acceler- ate) Problem: It is easier to change the velocity of a 1 kg object than a 2kg object. Select One of the Following: (a-Answer) True (b) False Solution True. Since the 1kg object has less inertia, it is easier to accelerate. Total Points for Problem: 2 Points Solution to On-Line Homework Problem 5.2(Linear Momentum is Proportional to Velocity) Problem: Linear momentum is proportional to velocity.

Unformatted text preview: tor times a scalar, linear momentum is a vector in the direction of the velocity. Total Points for Problem: 2 Points Solution to On-Line Homework Problem 5.3(Isolated Systems and Linear Momentum) Problem: It is possible for an isolated system to change its linear momentum. Select One of the Following: (a) True (b-Answer) False Solution False. Linear momentum is always conserved, but con-served can involve transferring something into or out of a system. An isolated system this means there is nowhere it can go, so it must stay constant. Total Points for Problem: 3 Points 2...
