Answer: C
produces as much as or more energy than it uses
Explanation:
This implies that the total energy used by the building is equivalent to the energy generated by the site
F equals ma
F/m equals a
a= 3 then
The change in momentum of the ball is 0.6Kgm/s.
To find the answer, we need to know about the momentum.
<h3>What's the expression of change in momentum during collision?</h3>
- The change in momentum= final momentum - initial momentum of the objects
- And momentum= mass × velocity
<h3>What's the change in momentum here?</h3>
- Here the initial momentum= 0.10×30=3Kgm/s
- Final momentum= 0.10×24= 2.4Kgm/s
- Change in momentum= 3-2.4= 0.6Kgm/s
Thus, we can conclude that the change in momentum is 0.6Kgm/s.

Friction made it difficult because an object in motion may not always stay in motion due to the friction caused by its movement. For instance, if you roll a ball down a straight platform, it will not go on forever. The friction of the platform and the ball with eventually slow it down and stop it.
