15. If the motion of one particle is dependent on that of another particle,
each coordinate axis system for the particles
A) should be directed along the path of motion.
B) can be directed anywhere.
C) should have the same origin.
D none of the above.
3. A particle is moving with an initial velocity of v = 12 ft/s and constant
acceleration of 3.78 ft/s2in the same direction as the velocity. Determine
the distance the particle has traveled when the velocity reaches 30 ft/s.
A) 50 ft B) 100 ft
C) 150 ft
9. A particle has an initial velocity of 30 ft/s to the left. If it then passes
through the same location 5 seconds later with a velocity of 50 ft/s to the
right, the average velocity of the particle during the 5 s time interval is
A) 10ft/s > B) 40ft/s>
6. A projectile is given an initial velocity Vo at an angle gabove the
horizontal. The velocity of the projectile when it hits the slope is
the initial velocity Va.
A) Less than B) Equal to
C) Greater than D) None of the above
