Homework Statement Kit the cat is going to jump through a hoop. He begins on a wicker cabinet at a height of 1.745 m above the floor and jumps through the center of a vertical hoop, reaching a peak height 3.115 m above the floor. With what initial velocity did Kit leave the cabinet if the...

Ah, my mistake. I redid it and got 68.67. I just checked and it is correct! Thank you! I will be able to solve for the angle :) I must have been too sloppy with the numbers, I realized my calculator was still keeping the negative number even while being squared, messing everything up. Thanks again!

92.037. I checked, not the right answer (for part a)

Ah, would it be at 180o?

Hi, as you can see I tried that. It did not work :( Do I sum both the x-coordinates? I had 31cos45 - 87 since they are on opposite sides of the coordinate grid.

Hi! I have tried what you said but still do not have the right answer. Here is my work: Excuse the writing, I'm in a car haha!

Ok, when I was initially taught this I was told to make a chart in both the x and y with what you know and do not know. The setup would be something like this: ______ X _____ Y a = vi = d = t = From there try to solve for maybe t using the y-variables (since you don't have that...

Here is the problem: I am sure I can use pythagorean theorem of quadratic equation to solve but to be honest I'm blanking ridiculously. I have tried setting it on a coordinate grid and finding the resultant, but I have had no luck! I know I've done this problem before in high school but I'm...
