Answer:
KE = 54450 J
Explanation:
Data:
- m = 900 kg
- v = 11.000 m/s
- KE = ?
Use the formula:
Replace and solve:
A kinetic energy of <u>54450 Newtons</u> is imparted to it.

I think that may depend on the individual viewer. I'm sure most people don't even notice it. To me, it sometimes becomes nocuous.
Answer:
When traveling behind other vehicles, there should be at least a four second space between your vehicles. When the car in front of you passes a stationary object, slowly count to yourself. If you pass the object before the allotted time, you should back off. When traveling at night or inclement weather, these times should be doubled.
Don't talk on a cell phone while driving. Phones detract from your ability to concentrate on the road and increase your chance of a collision by nearly 400%. If you must use the phone, pull over to a safe, well-lit parking lot and place your call there. After completing your call you may continue on your way.bey all speed limits and signs.
Specific heat of a substance can be calculated using the equation q=mst, where “q” is heat applied to the system, “m” is the mass of the substance, “s” is the specific heat, and “t” is the change in temperature. In this case,
q=mst
(1495 J)=(339 g)(s)(+11 degrees C)
s=0.401 J/g•degrees C.
The specific heat of this substance is 0.401 J/g•degrees C). However, the problem is asking for the heat capacity of the metal, which is defined as C=ms using the same definitions as above. In this case, the heat capacity of the metal works out to be 135.91 J/g.
Hope this helps!
