PLEASE HELP: Use Newton’s second law of motion to determine the unknown values for the following objects in motion. Assume all objects are being accelerated on frictionless surfaces or through frictionless mediums. Calculate the values, and round your answer to the correct number of significant digits. If needed, use the conversion factor 1 lb = .454 kg.
Baseball data: 0.142 kg, 1._N, 388 m/s2
Football player data: 0.426 m/s2 , 2._kg, 28.39 N of force pushing the player over the goal line, and 1.98 N of force by defender pushing in the opposite direction
Wagon data: 77.6 lbs,128 N, 3._m/s2

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
