Steve, thank you for replying. I'm sorry but I'm not exactly sure why you used the function y(t). also I don't know if that's a specialized equation. We are only supposed to use the 4 kinematic equations.
Ok thank you! I accidentally miscalculated my hypotenuse... so now my final answer is: 108.14 miles 56.6°East of South, because it passes the third quadrant by 19.6° which is why you subtracted 90°
or actually that is what you said, sorry.
if I did it my way, would I be taking steps to solve the problem?
Ok, so I am guessing I need to use the angle given to me. Now I have to find the hypotenuse length and angle? I think?
Whoops sorry forgot to give my value after doing the calculation. My answer is: 110.4 miles, the miles squared gets square rooted so then it becomes just miles, right?
well, this was what I decided to go with. since it has designated that he made a 90° turn; We can indicate that it is a right triangle. So, I performed this: √( (59.5)^2 + (93.0)^2 )
