1. Determina la fuerza con la que es lanzada una pelota de golf de 0.156kg a una aceleración de 5m/s2 con la ley de newton. 2. ¿Cuál es la aceleración que adquiere un objeto que tiene una masa de 12kg y es empujado con una fuerza de 20N?

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

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?
