To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity. ▾ Part A A plane accelerates from rest at a constant rate of 5.00 m/s² along a runway that is 1800 m long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time tro needed to take off? Express your answer in seconds using three significant figures. ▸ View Available Hint(s) tro= 26.8 s Submit ✓ Correct If you need to use the answer from this part in subsequent parts, use the unrounded value you calculated before you rounded the answer to three significant figures. Recall that you should only round as a final step before submitting your answer. Part B Previous Answers What is the speed UTO of the plane as it takes off? Express your answer numerically in meters per second using three significant figures. ▸ View Available Hint(s) UTO 134 m/s Submit Previous Answers ✓ Correct If you need to use the answer from this part in subsequent parts, use the unrounded value you calculated before you rounded the answer to three significant figures. Recall that you should only round as a final step before submitting your answer.

▼ Part C What is the distance dfirst traveled by the plane in the first second of its run? Express your answer numerically in meters using three significant figures. ► View Available Hint(s) dfirst = 2.50 m Submit Part D Correct If you need to use the answer from this part in subsequent parts, use the unrounded value you calculated before you rounded the answer to three significant figures. Recall that you should only round as a final step before submitting your answer. dlast Previous Answers What is the distance diast traveled by the plane in the last second before taking off? Express your answer numerically in meters using three significant figures. ► View Available Hint(s) = 132 m Submit Previous Answers Correct Important: If you use this answer in later parts, use the full unrounded value in your calculations. Since the plane is accelerating, the average speed of the plane during the last second of its run is greater than its average speed during the first second of the run. Not surprisingly, so is the distance traveled. If you need to use the answer from this part in subsequent parts, use the unrounded value you calculated before you rounded the answer to three significant figures. Recall that you should only round as a final step before submitting your answer.
