Thank you, Tim! That really helped. Is it also alright to use the formula v-Proj(v onto u) to solve this (provided we are given vector v)? I've tried to solve similar questions that way and ended up with a different answer. Not sure why this may be.

Sarah, that method should work. Perhaps you are making some simple mistake in the calculation.
