Assume all positions refer to the center of the ball.

Dwyane Wade shoots a lot of free throws. When he lets it go, it's 15 feet from the basket, and 7 feet off the ground. When the ball reaches its maximum height, it is 13 feet high. When the ball goes through the hoop, it is zero feet from the basket and 10 feet high.

Set this problem up so that the y-axis is a line through the center of the basket, and the x-axis is a line on the floor from under the center of the basket to directly under Mr. Wade.

Find the equation of the parabola that matches the ball's trajectory.

Best answer will explain the process.

My answers came out to:

(a) 45.1 m/s

(b) 4.59 s. Or, should this be 4.59s * 2?

Thanks.

If your dog dies and in the future you make a time machine to go back in time to save him, will it work? Of course not, if you in fact made a time machine to save your dog, and were successfull in your attempt then why would your past self need to make a time machine to go back in the first place? Does anyone know of any good books that talk about the theories of paradox? I love the concepts of time travel and paradox together and am looking for a good read.

The Hayward Fault doesn't go through Pittsburg, Ca, but is about 30 miles away. If there is a major Earthquake from that fault line, I'm pretty sure we would feel it, but would it cause any life threatening damages? Is there an estimated time we can expect a "big one"?
