Newtons Second Law-2021

According to the second law of motion, an object acted upon by a force will accelerate in the direction of the force. If no forces act on an object, the net force on the object is zero. If there is just one force on an object, then that force is the net force. If 2 forces push or pull on an object in opposite directions, and the two forces cancel each other exactly, the net force is zero. If two forces act on an object in opposite directions and they don't exactly cancel, what is left over is the net force (the difference in the forces). In the diagram, the net force is 2 Newtons to the right. If two (or more) forces act on an object in the same direction, the net force is the sum of the forces. In the diagram at left, the net force is 10 Newtons to the right. Sort the following statements on whether they describe mass or weight. Mass =F dependent on the internal makeup of an object only Weight depends on location and gravitational field =m*a Answer the following questions. Type whole numbers only without units. Jessica is a ballet dancer who's mass is 54 kg on earth.1. What is her weight in N on earths surface? 529 N2. Given that 1 kg is equal to 2.2 lbs on earths surface, what is her weight in pounds? 119 lbs3. What would be Jessica's mass on Mars? 54 kg4. What is Jessica's weight on Mars in N (g= 3.8 m 205 N Fill in the table below.

Complete the table below assuming there is 50 N of air resistance. Use whole numbers only. Hint: Subtract the air resistance from the applied force then f=ma.
