Lecture 2 Mathcad basics and Matrix Operations - essie-uf
... IMPORTANT: Another example: Say we create a 1-D vector x with the following: x := [2 4 9 5 2]; Now say we want to square each number in x. It would seem natural to do this: y := x^2 But Mathcad tells us: “This Matrix must be square. It should have the same number of rows as columns” Note that y : = ...

Momentum and Impulse
... Note that "isolated" means that no external force acts on the system, which is a set of interacting objects. • If a system does have a net force acting, then the momentum changes according to the impulse equation. ...

... Two canoes collide in a river and come to rest against each other. A person in one of the canoes pushes on the other canoe with a force of 56 N to separate the canoes. The mass of a canoe and occupants is 150 kg and the other canoe and occupants has a mass of 350 kg. The length of each canoe is 4.55 ...

... §3.2, p. 126, #19 Let A be an n × n matrix. Prove that the following statements are equivalent. (a) N (A) = {0}. (b) A is nonsingular. (c) For each b ∈ Rn , the system Ax = b has a unique solution. Solution: Our strategy is to show that (a) implies (b), that (b) implies (c), and that (c) implies (a ...
