A spider crawling across a table leaps onto a magazine blocking its path. The initial velocity of the spider is 0.890 m/s at an angle of 33.6° above the table, and it lands on the magazine 0.0750 s after leaving the table. Ignore air resistance. How thick is the magazine? Express your answer in millimeters.

hf= vivert*t-g t^2

vivert= .89sin33.6 solve for hf.
