a student performing the centripetal force experiment added some mass to the 25.0g acceleration block. when he did the experiment, he found that the speed at which the accelerated block separate from the magnet was 102 m/s^2. The radius of the circular motion before breakaway was 9.00 cm and the magnetic force between the accelerated block and magnet was .750N. A) calculate the mass added to the accelerated block. B)suppose the radius of the circular motion before breakaway was decreased to 8.00 cm, and nothing else was changed. calculate the new breakaway speed
