Um of momenta = 0( Since both the cars stop)
<span>Let m1 be the mass of the cadillac and m2 be the mass of the volkswagen. </span>
<span>then, v1=speed of cadillac and v2=speed of volkswagen. </span>
<span>Therefore, (m1)*(v1) + (m2)*(v2) = 0 </span>
<span>Substituting, </span>
<span>(1000*4) + (2000*v2) = 0 </span>
<span>4000 = - 2000 v2 </span>
<span>Therefore, v2= - 2 m/s. </span>
Answer:
A pre-existing weather disturbance: A hurricane often starts out as a tropical wave.
Warm water: Water at least 26.5 degrees Celsius over a depth of 50 meters powers the storm.
Thunderstorm activity: Thunderstorms turn ocean heat into hurricane fuel.
The total energy produced by the generator is 3.45 kJ. Of this energy, 2.23 kJ are lost because friction and electrical resistance, so this amount of energy is converted into thermal energy. This means that the rest of the energy is available as electric energy, and it is equal to:
Explanation:
Power = work / time
Work = force × distance
Therefore:
Power = force × distance / time
Since the distance is the same, he would have to either increase the force he exerts or decrease the time (increase his velocity) in order to increase the amount of work done.
