Can someone please help me with science.

Aballet student who learns with the of his instructor is demonstrating learning.

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?
