The site from which an airplane takes off is the origin. The x axis points east; the y axis points straight up. The position and velocity vectors of the plane at a later time are given by 1 = (1.61 x 10‘î +3.00 x 10°j) m and 7 = (150i+21j) The plane is most likely just touching down. in level flight in the air. ascending descending taking off

5 pts The site from which an airplane takes off is the origin. The x axis points east; the y axis points straight up. The position and velocity vectors of the plane at a later time are given by i = (1.61 x 10°î +3.00 x 10°j) m and 7 = +(150i – 21ſ) The plane is most likely O just touching down. in level flight in the air. O ascending. O descending. O taking off.
Question 15 5 pts The site from which an airplane takes off is the origin. The x axis points east; the y axis points straight up. The position and velocity vectors of the plane at a later time are given by 1 = (1.61 x 10'î +3.00 x 10°j)m and 7 = (1soi +213) The plane is most likely O just touching down. in level flight in the air. ascending O descending. O taking off.
Question 21 10 pts An airplane takes off from rest. It accelerates 4 m/s2 for 35 seconds. What is its velocity at the end of the acceleration? How far did it go in the 35 seconds? Question 22 10 pts A boat sails 100 km east then 200 km 60° south of east. How far and which way is it from the origin?
Student Name 1. A particle confined to motion along the x axis moves with constant acceleration fromx = 2.0 m to x 8.0 m during a 2.5-s time interval. The velocity of the particle at x - 8.0 m is 2.8 m/s. What is the acceleration during this time interval? 2. The polar coordinates of a point are r=5.50 m and Angle 240°. What are the Cartesian coordinates of this point? 3. On occasion, the notation A= [A, O] will...
Heres example 10.2 (3) (30 points) In Example 10.2, the moment of inertia tensor for a uniform solid cube of mass Mand side a is calculated for rotation about a corner of the cube. It also worked out the angular momentum of the cube when rotated about the x-axis - see Equation 10.51. (a) Find the total kinetic energy of the cube when rotated about the x-axis. (b) Example 10.4 finds the principal axes of this cube. It shows that...
