Question 15

Item 15 Review | Constants Part A A boat of mass 250 kg is coasting, with its engine in neutral, through the water at speed 1.00 m/s when it starts to rain with incredible intensity. The What is the speed of the boat after time 0.500 hr has passed? Assume that the water resistance rain is falling vertically, and it accumulates in the is negligible. boat at the rate of 100 kg/hr . Express your answer in meters per second. View Available Hint(s) 0.833 m/s Submit Previous Answers CorrectY FartEi Now assume that the boat is subject to a drag force Fa due to water resistance. Is the component of the total momentum of the system parallel to the direction of motion still cons shred? yes no Previous Answers 1/ Correct The boat is subject to an external force. the drag force due to water resistance: and therefore its momentum is not consented. Part C The drag is proportional to the square of the speed of the boat, in the form Fa = but where b = 0.5 N. $2/m. What is the acceleration of the boat just after the rain starts? Take the positive axis along the direction of motion. Express your answer in meters per second per second. > View Available Hint(s) VO AEd m/82 Submit Previous Answers
