In a perfectly inelastic collision, while doing bullet/ pendulum experiment through simulation, there were some sources of error( experimental factors)that may affect, the value of final velocity and final kinetic energy. what are those factors? and what would be the souces of error if we perform a physical experiment rather than a simulation? and how it would affect our final velocity. compare results in the simulation and physical experiment

If a firm has $230,000 total assets and $150,000 in net income reported on its 2016 financial statements, $220,000 total assets and $160,000 net income on its 2015 financial statements, and $200,000 total assets and $170,000 total income on its 2014 financial statements, then the firm's return on assets (ROA) for 2016 is __________.

65.2%

(Net income for 2016) / (Total assets of 2016 + Total assets of 2015) / 2

equal to net income for 2016 divided by total assets of 2016
