A 12.0-kg block is pushed across a rough horizontal surface by a force that is angled 30.0◦ below the horizontal. The magnitude
Juli2301 [7.4K]

Answer:

157.36 N

Explanation:

Contact force is the force which is created due to contact and it is applied on the contact point . The force applied by body on the surface is its weight .

If R be the reaction force of the ground

R = mg + F son30

= 12 x 9.8 + 75 sin 30

= 117.6 + 37.5

= 155.10 N .

friction force = f

Net force in forward direction = F cos 30 - f  = ma

75cos 30 - f = 12 x 3.2

f = 65 - 38.4

= 26.6 N  

Total force on the surface =√( f² + R² )

√ (26.6² + 155.1²)

= √707.56 + 24056²

=√ 24763.57

= 157.36 N.

contact force = 157.36 N .

Do you feel it is safe for rock concerts to reach these high decibel levels, or do you feel sound levels should be regulated? If
statuscvo [17]
I feel that they should be regulated, mostly because its not safe for your ears to listen to such loud music. For example, if you were in the front of the concert you are more likely to get damage of your hearing more then the people in the back who have a slight chance.

Now, our ears can only handle up to 85 dB, thats why when you shoot a gun in a shooting range (if you've been at one) you wear hearplugs to protect you from the roughly 140-dB it gives off when fired. At rock concerts roughly 120-dB only 35-dB higher then what we are able to handle. The limit should be at most 90 dB because it is not too high and wont give us full on hearing damage to us in the future.
