A 100 N force is applied at an angle of 40° to the horizontal to move a 10 kg object at a constant speed for a horizontal distance of 5 m. How much work is done?

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of

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 distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
