Answer:
Normal force=mg
Explanation:
The reaction force of weight is the normal force.
in order to find the normal for we need to write all the forces and set it equal to the net force:
N-mg=ma (since it is a constant speed the a=0)
N=mg
Density =mass/volume 120/200 =0.6 g/cm
Acceleration is equal to the change in velocity per unit time. In this case, velocity has changed from 17.7 m/s to 14.1 m/s, which is a decrease of 3.6 m/s. This takes place in 12 seconds, so the average acceleration is 3.6 m/s / 12s = 0.3 m/s^2. The direction of this acceleration is south, since the car's northbound speed is decreasing.
Answer:
it would be the cord will have the most energy at the moment.

Answer:
Explanation:
Our knowable variables are <em><u>velocity and time</u></em>
We know that 
<em><u>So, with the data that we have we can </u></em><em><u>calculate distance</u></em>
