1. A person is walking on a treadmill. The treadmill is moving backwards at a speed of 3.0 m/s. The person is
moving forward relative to the treadmill at 2.5 m/s. What is the person’s velocity relative to the ground?
2. An airplane travels east at an air speed of 400.0 m/s into a head wind of 35.0 m/s. What is the airplane’s
ground speed?
3. A hiker travels 5.0 km north and then 2.5 km west. What is the resultant displacement vector?
4. A hiker travels 45.0° north of east for 25.0 km. What are his or her north and east displacement components?
5. A car travels down a highway with a north velocity component of 15.0 m/s and an east velocity component of
50 m/s. What is the resultant velocity vector?
6. A car travels 55.0° west of north at 45.0 m/s. What are the resultant north and east velocity components?
7. A ball is launched from ground level. After 15.0 s the ball is 14.5 m above the ground and horizontally 25.0 m
from the launch point.
a. What is the resultant displacement vector?
b. What is the vertical average velocity component?
c. What is the horizontal average velocity component?
d. What is the resultant average velocity vector?
8. A marble rolls down a 1.55 meter ramp that is at an angle (to the positive x-axis) of 150.0°. The marble is at
rest at the top of the ramp and reaches the bottom of the ramp in 1.95 seconds. Assume constant
acceleration.
