Answer:
8018.2 N
Explanation:
Change in momentum, p is equivalent to force * time
M(vf-vi)=Ft where M represent mass of the car, vf is the final speed, vi is the intial speed of the car, F is the force in queation and t ia the time.
Since the car finally comes to rest then the final velocity ia zero. Substituting 1400 Kg for M, 0 for vf, 27 m/s for vi and 1.5 s for t then the first force is
1400(0-27)=1.5F
F=25200 N
Similarly, when we work with the same values but t changed to 2.2s
1400(0-27)=2.2 F
F2=17181.818181818 N
Reduced force will be 25200-17181.818181818=−8,018.181818182N
Approximately, 8018.2 N

Good
- </span><span>The reason that people and animals can walk. Because of friction we are able to walk one foot to the other.
- Prevents accidents, like being able to slam on a cars break and sliding endlessly.
Bad:
- When trying to go faster, friction can prevent that. In a car, or even trying to roller skate.
- It will damage the object that is sliding. Weather its skinning your knee of busting a tire. </span><span><span>✡</span>

Correct answer choice is :
A) Atmospheric composition
Explanation:
A radiosonde is a battery-powered telemetry device transmitted into the environment normally by a weather balloon that regulates several atmospheric parameters and sends them by radio to a ground receiver. The radiosonde is a small, expandable device unit that is recessed below a six-foot-wide balloon inflated with hydrogen or helium. As the radiosonde stands at about 1,000 feet/minute, sensors on the radiosonde measure forms of pressure, temperature, and related moisture.
