Rufina [12.5K]

Answer:

 N = 23.4 N

Explanation:

After reading that long sentence, let's solve the question

The contact force is the so-called normal in this case we can find it by writing the translational equilibrium equation for the y axis

            N - w₁ -w₂ =

            N = m₁ g + m₂ g

            N = g (m₁ + m₂)

let's calculate

            N = 9.8 (0.760 + 1.630)

            N = 23.4 N

This is the force of the support of the two blocks on the surface.

Suppose that Lisa walks her dog around the block for a little exercise. The block is 1 mile around. If she walks around the bloc
Alina [70]

Displacement is defined as the net distance traveled through the entire trip. That is to say, if you compared where you are at the end of the walk to where you were at the start, the displacement is the distance between those two points.


Distance doesn't compare the two end points. It just counts the total distance you've walked throughout your trip.


Lisa walks once around the block. She starts and ends at the same place. Her displacement is therefore 0 m.


But she has walked 1 mile throughout the trip. Her distance walked is therefore 1 mile.
