Chapter 5.1 and 5.2 Formative Assessment
Equations:
1. A salesperson leaves the office and drives 26 km due north along a straight highway. A turn
is made onto a highway that leads in the direction 30.0° north of east. The driver continues
on the highway for a distance of 62 km and then stops. What is the total displacement of
the salesperson from the office?
2. A heavy box is pulled across a wooden floor with a rope. The rope forms an angle of 60.0°
with the floor. A tension of 80.0 N is maintained on the rope. What are the horizontal and
vertical components of the force?
3. A hiker leaves camp and walks 10.0 km due north. The hiker then walks 20.0 km in the
direction 45° west of north. What is the total distance the hiker walks?
4. A 525-N trunk is placed on an inclined plane that forms an angle of 30.0° with the
horizontal. What are the components of the weight parallel to the plane and normal to the
plane?
5. A child with a mass of 30.0 kg is moving down a slide at a playground. The angle the slide
makes with the ground is 60.0°, and the coefficient of friction between the child and the
slide is 0.250. What is the frictional force on the child?
