Aperson walks 25.0° north of east for 3.10 km. how far due
north and how far due east would she have to walk to arrive at
the same location?

Explanation:

Use sine and cosine to find the vertical and horizontal components.

31.0 km × sin 25.0° = 13.1 km north

31.0 km × cos 25.0° = 28.1 km east

She would have to walk 13.1 km north and 28.1 km east.

the body's situation won't change the forces are equal opposit and on the same body

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
