Can you answer the following multiple choice physics questions. Just the answer would be fine no need to show your work.

1. Which of the following best describes a free- body diagram? - a simple drawing that shows all the forces acting on an object - a sketch showing all the objects involved in a situation - a diagram that represents a specific area drawn to scale - a diagram showing the network of a multi- body system 2. For the freebody diagram attached, calculate the net force acting on the object. - 70 N [W] 70 N [E] - 18 N [W] - 18 N [E] 3. A net force of 42 N is applied to a soccer ball with a mass of 0.35 kg. Determine the acceleration of the soccer ball. 42 m/s^2 [Forward] 120 m/s^2 [Forward] 120 m/s^2 [Backward] - 150 m/s^2 [Forward] 4. Which of the following is a pulling force from a rope or a string on an object? - Normal Force - Tension Gravitational Force - Applied Force 5. A painter (85kg) climbs 2.0m up a ladder in 3 seconds, calculate their power. - 270 W - 555 W 833 W 1666 W 6. Which collision has momentum conserved but not kinetic energy? - closed - explosion - inelastic - elastic 7. A 5.0-kg cat travelling at 1.3 m/s [E] has a momentum of - 6.5 m/s [W] - none of the above - 6.5 m/s [E] - 3.8 m/s [E] - 3.8 m/s [W] 8. A net force of 12 N changes the momentum of a 250-g ball by 3.7 kgxm/s. The force acts for -1.2 s - 3.2 s - 0.31 s - 44 S - 0.81 s
