I need help with these two physics problems please help I'm very confused
1.Angela pulls a wagon of mass 5 kg and it accelerates at a rate of 0.2 m/s^2. What is the net Force in Newtons?
2.Order these objects by the amount of inertia they have, from least to greatest. The Empire State Building. An insect. An atom. Mount Everest. The Sun. A human. A Planet. A DNA molecule. A bacterium. A cat. |

1. Use F=ma; you have values for both 'm' and 'a,' so plug them in and do the math.
2. The inertia of an object is equivalent to its mass, and that's proportional to how much the thing weighs. For example a mountain weighs more than a cat, so a mountain has more inertia than a cat. Put the list in order of increasing weight and you'll have it. |
