Nikolas had an idea that he could use the compressed carbon dioxide in a fire extinguisher to propel him on his skateboard. Nikolas, the fire extinguisher and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.2m/s^2 Round your answer to the nearest whole newton GON Which of Newton's laws did Nikolas have to use to calculate this force?

Which statement best summarizes the central idea of "Applications of Newton's Laws"? Newton's laws can explain the forces that occur between objects every day. Newton's laws are useful for explaining why we should make good decisions. People should use caution when moving objects, due to objects' inertia. Newton's laws are outdated and cannot be used for present-day problems and situations.
