I happen to be working on this same problem right now (University of rochester, ECE 111?) Wouldn't the currents of each input always equal zero?

So I would plug those values into the forumula, and then add all of the outputs together?

Why do you find the x[n] values for a sine wave when the question is asking about a cosine wave?

So am I right in saying x[0]=1 x[1]=0 x[2]=-1 x[3]=0 x[4]=1 for a cosine wave?

I've been working on this problem for around three hours, and I'm getting nowhere... I think it may be that I don't have even the most basic grasp of the material to even get a decent start on the problem, but hopefully someone here will be able to help me... Homework Statement Calculate...

Awesome, thank you guys so much for the help!

Ok, so then 0 = 1.5 + v(2) - 20 18.5 = v(2) So the initial velocity would be 9.25 m/s?

I guess I meant initial position when I said height. So would that make x(t) 0?

Homework Statement Suppose you adjust your garden hose nozzle for a hard stream of water. You point the nozzle vertically upward at a height of 1.5m above the ground. When you quickly move the nozzle away from the vertical, you hear the water striking the ground next to you for another 2.0...
