You are on an airplane traveling 30° south of due west at 180 m/s with respect to the air. the air is moving with a speed 31 m/s with respect to the ground due north.
1) what is the speed of the plane with respect to the ground?
2) what is the heading of the plane with respect to the ground? (let 0° represent due north, 90° represents due east).
3) how far east will the plane travel in 1 hour?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
