He force with which the wind pushes the stone is a drag force. Assuming a stone of mass 25 kg has a vertical cross-sectional area of 0.05 m2, a drag coefficient C=0.7C=0.7, and the air density is 1.21 kg/m3, what is the wind speed along the ground needed to maintain the stone's motion once it has started moving? INCLUDE UNITS in your answer!

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.)

answer(20) psi;
