The total amount of heat released from the passive solar house is:
The mass of water required to maintain indoor air temperature is:
Answer:
Explanation:
Data:
Calculation:
This is a perfectly inelastic collision. The two carts stick together after the collision and move with a common final velocity.
The conservation of momentum equation is
Answer:
2 Newtons
Explanation:
Therefore, your mass would be 1kg and your acceleration would be 2m/s/s
Plug the numbers into the equation:
which will equal
An impact which stops a moving object must do enough work to take away its kinetic energy, so extending the distance moved during the collision reduces the impact force.
