Two dimensional vectors question

  • #1
Hello, I'm having issues with a question like the following...


A spider crawling across a table leaps onto a magazine blocking its path. The initial velocity of the spider is 0.830 m/s at an angle of 31.0° above the table, and it lands on the magazine 0.0640 s after leaving the table. Ignore air resistance. How thick is the magazine?


I just can't seem to figure out how to figure it. I've tried using V0yT -1/2gt2
With V0y = .830sin31 = .42748...
T = .0640s
and G = 9.8m/s2

But when I put it together I just can't seem to get the answer right. Am I using the wrong equation or what equation should I use? Any help with be much appreciated!

your work looks correct. when i use your numbers i get:

thickness = 0.0072576 m

is this the result you are getting?

Hmmm. No it wasn't for some odd reason. I kept getting a much lower number for some reason... I'm probably doing something wrong with the calculator.
