Afootball is kicked from the ground with a velocity of 38m/s at an angle of 40 degrees and eventually lands at the same height. what is the direction and magnitude of the ball's velocity 0.2 seconds after impact?

Initially, the velocity vector is . At the same height, the x-value of the vector will be the same, and the y-value will be opposite (assuming no air resistance). Assuming perfect reflection off the ground, the velocity vector is the same. After 0.2 seconds at 9.8 seconds, the y-value has decreased by , so the velocity is .

Converting back to direction and magnitude, we get

where is the photo and the answer choices?

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
