Problem 1. You hit a bowling ball with a mallet, starting from rest. Every time you hit it, its velocity increases by exactly 10 cm/s. You start timing (t 0 seconds) at the instant you hit the ball the first time, and you hit it once every second. Two simplifying approximations: (1) Suppose each hit is very short, so the speed changes in a short amount of time and (2) suppose the ball doesn't slow down between hits a. Att...

Consider the diffusion equation, au(x,t u(x,t) Here u(x,t) > 0 is the concentration of some diffusing substance, the spatial variable is x, time is t and D is a constant called the diffusivity with dimensions [LT-11. We will consider the diffusion equation on a finite spatial domain (0<x< 1) and an infinite time horizon (t > 0). To solve the diffusion equation we must include...
