A jogger runs with a speed of 3.00 m/s in a direction 25.0 degrees above the x axis.?

I think this might be right. Make a right triangle. The hypotenuse would be 3 m/s. You would do cos 25. Cos=a/h so it would be cos 25= a/3. 3cos 25= 2.72 m/s. This would be your x component. To find the y component do cos 65 because it makes a right angle and 90-25=65. Cos65= a/3. 3cos65=1.27 m/s. This woud be your y component. And for the second part just divide the speeds in half and do the same thing again. I believe this is the right way. Good Luck mane.
