A ball of mass m moving with velocity Vi strikes a vertical wall. The angle between the ball's initial velocity vector and the wall is θi. The duration of the collision between the ball and the wall is Δt, and this collision is completely elastic. Frictio...

Since g is a common factor, you may remove it and just do the "work" as normal arithmetic: (1/2)g + (-g) = g * (1/2 - 1)

Isn't Jamal a man's name?

The sum of two lengths must be greater than the third.

"Positively" in which direction?

It's also not a prediction if the dates are in the past.

Wow. Algebra and Real Analysis. I hope this isn't a high-school problem!

But anyway, to get you started just look at the definition of metric spaces. In this case, note that: (a) p(f, g) >= 0 (this should be clear), and as |f - g| = 0 iff f == g. (b) p(f, g) = p(g, f) (because of the way modulus works). Finally, see whether: (...

Why not try and trick one of your other profs to do this for you?

Don't tick off the mafia.

Whoops, I meant p(f, h) <= p(f, g) + p(g, h) for (c).
