Answer:
The distance travelled does not depend on the mass of the vehicle. Therefore, 
Explanation:
This deceleration situation can be analyzed by means of Work-Energy Theorem, where change in translational kinetic energy is equal to the work done by friction:
(1)
Where:
- Mass of the car, in kilogram.
- Initial velocity, in meters per second.
- Coefficient of friction, no unit.
- Travelled distance, in meters.
Then we derive an expression for the distance travelled by the vehicle:
As we notice, the distance travelled does not depend on the mass of the vehicle. Therefore,
According to the saving of the momentum, the total momentum before collision is equal to the total momentum after collision
<em><u>in symbols:</u></em>
<em>
</em>
thus
then, the initial momentum of the second cart
Answer:
high number of coils in the wire
There are many other renewable sources to use such as hydro power, and wind power. All of these are renewable and safe to the environment. One reason solar power may not be used is because of it's cost.
