Task 3 As a part of your role in the motion and dynamics analysis department, you have been asked to design a mission consists of airplane and boat. The mission target is to deliver a package by the airplane that must be picked by the boat. You must provide two analysis steps to solve the problem: 50 m/s Package Figure.2: Package of emergency supplies Part 1 • The airplane traveling horizontally at 50 m/s • The airplane is 150 m above the sea 9. Write the displacement vector r* as a function of time and find by calculus the acceleration vector a". 10.

rcise No 4 Two birds flew in two different random directions from the same point on tree. Bird A moved with a velocity V of 37 mph in the direction of 37° south of east. Bird B moved with a velocity Va of 30 mph in the direction of 30° west of south. Both velocities are vectors with the given magnitudes and directions. (a) Convert the unit of each velocity vector from mph to m/s and show your detailed work. (b) Draw vectors V and Vs on an xy-Cartesian plane then draw the resultant vector of the two. Break vector V into components and write the result in terms of unit vector notation. (c) (d) Break vector Vs into components and write the result in terms of unit vector notation. (e) Add the two vectors and write the resultant vector in unit vector notation. (f) What is the magnitude of the resultant vector? (g) In what direction is the resultant vector pointing? Write the answer in terms of an angle with the proper indication of the direction.
Roughly sketch the particle's displacement over time. Indicate the particle's location at points A, B, C, D, and E, as well as how the particle moves berween these points (whether parabolic/linear). Lastly, label the instants A, B, C, D, and E on your graph.
For the problems below, complete the procedural instructions for each problem. Question 1: A helicopter flies with an airspeed of 42.5 m/s [W]. If the wind is traveling with a velocity of 25.0 m/s [E30°S] relative to the ground then determine the velocity of the helicopter relative to the ground. a. Use the data from the question to determine the velocity components for the helicopter's speed relative to the air and the wind's speed relative to the ground. b. Use your velocity components from part (a) and determine the resultant velocity for each component. (In other words, determine the resultant horizontal component for the helicopter's ground speed and the resultant vertical component for the helicopter's ground speed). c. Using your data, determine the resultant velocity of the helicopter relative to the ground.
