In the image below, astronauts detect approaching space junk and become concerned. They realize that the object has high velocity in the direction of
the station and will damage it if they do not do something to avoid it. They are
concerned because of Newton's _ law of motion.
A. Fourth
B. First
C. Second
D. Third

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
