In a controlled automobile collision, a 44-kilogram crash-test dummy moving at 15 meters per second is brought to rest by a seat belt during a 0.10-second time interval. What is the magnitude of the average force exerted on the dummy during this interval

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?

What characteristics of hv2112 make it the best candidate to be classified as a thorne-zytkow object?
