A velocity vector 55 degrees below the positive x-axis has a y-component of -13 m/s.

Ive tried many different ways for this problem but i keep getting it wrong! help!

Welcome to PF.

If your vector is pointing 55° down then draw the diagram.

You have a triangle - you have the angle - they tell you a side - then figure out the length of the hippopotamus.
