An aircraft performs a maneuver called an aileron roll. During this maneuver, the plane turns like a screw as it maintains a straight flight path, by using its ailerons to set the wings in circular motion. If it takes the plane 35s to complete the circle and each wing length is 4.6m, what is the acceleration of the wing tip?O A. 0.69 mis?OB.0. 15 m/s?OC14 mis?OD.6.7 mis?

Time taken to complete 1 circle (T) = 35 seconds Length of wing (L) = 4.6 m

Answered: An aireraft performs a maneuver called…

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 130 km and 25.0 of west, then 5.10 km due east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?
