Suppose you have to move a heavy crate of weight 875 {\rm n} by sliding it along a horizontal concrete floor. you push the crate to the right with a horizontal force of magnitude 300 {\rm n}, but friction prevents the crate from sliding. now assume that the crate is sliding along the floor with constant velocity. what is the magnitude f_p of the force you need to exert on the crate to make it continue to slide along the floor with constant velocity?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
