 Your company, Zevo Simulations, tasks you with the completion of a "projected trajectory simulator" for your boat crossing the river. You are not sure why this would be necessary, but you decide to proceed with the project. This simulator must display the motion of the boat crossing the river, with respect to the shore. The previous design team has already done the majority of the work, but they mysteriously disappeared without completing it... The head of the division suggests you complete the project as quickly as possible! Your company, Zevo Simulations, tasks you with the completion of a "projected trajectory simulator" for your boat crossing the river.
