2. Select the checkboxes: Forces, Values, Masses and Speed Force Values Masses Speed 3. Push the skateboard and the box with a force of 500N. Observe and describ behavior of the velocity once the skateboard is released Explain the reason of such behavior Part III. Friction 1. Click on "Friction" 2. Select the checkboxes: Forces, Sum of Forces, Values, Masses and Speed. Kee the knob that regulates the friction at the center of the scale. Forces Sum of Forces Values Masses
3. Start to push the box, increasing the force applied on the box slowly. There is a force that is opposite to the force you are applying. What is the name of the force opposing to the motion? 4. Once the box start moving, the magnitude of the resultant force increase instantaneously. How do you explain that? 5. Push the box and find the force needed to make the box to start moving. Add more mass (box, kid, man,refrigerator, basket as needed) and repeat the procedure such that you complete the table below. Hint: Weight = mass x gravity Magnitude of Normal Force = Magnitude of the Weight Mass (kg) Weight (N) Normal Force (N) Force of Static Friction (N) 50 90 130 150 180 x 0 N

Answer:
The total distance is 105 kilometers, and the total displacement is 15 kilometers east.
Explanation:
A truck moves 60 km east and then 45 km (60 - 15) back to west. The total distance will be,
Distance = 60 + 45 = 105
Distance is a scalar quantity that refers to the total space covered by a truck (object).
Displacement is a vector whose length is the shortest distance from the initial to the final position of a point undergoing motion.
The truck moves from Point A to Point B, covers 60 km. Then the truck turns back from point B to point C, 15 km away from the point A. So the displacement will be
Displacement = 60 - 45 = 15
Displacement is the difference between point A and C.
