Solve 2D Motion Problem: Ball Hitting Canyon Edge

Click For Summary
SUMMARY

The discussion centers on solving a 2D motion problem involving a ball with a velocity of 10 m/s that flies off the horizontal edge of a canyon defined by the equation y² = 16x. The user attempted to express the ball's motion as a function of x, resulting in the equation y = 4√x, but struggled with the mathematical solution. The correct approach involves plotting the curves derived from the canyon equation to visually identify the intersection points, which represent the coordinates where the ball hits the canyon.

Ok, in this problem a ball with velocity 10m/s flys off the horizontal edge of a canyon, the equation for the canyon is y^2=16x and it wants you to find the x,y cordinates where the ball hits it. I turned the balls motion into a a function of x for y and then set that equal to y=Sqrt(16x) but I can't solve it. It is an easy problem the book says but I can't do the math, or perhaps its my method, to figure it out. Thanks a lot for any help.

If you solve y^2=16x for y, you get y=4*Sqrt[x] and y=-4*Sqrt[x].

Plot the two curves and decide for yourself which one looks like a canyon. I think you should be able to solve it then.
 
Thanks, I am really dumb and was doing my equations wrong :)
