    Please answer the last 4 bullet points step by step. Again the last 4 bullet points. k III.pdf 1) Up until now we have always ignored air resistance. We should now add . Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but 2 with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bu. The coefficient b is a constant. (For this...
