The answer is Providing national parks
Answer:
10800 kg m/s
Explanation:
Since the dumpster was initially at rest, its momentum before collision equal to zero. So that the total momentum of the car and dumpster before collision is 10800 kg m/s.
The principle of conservation of linear momentum states that: in a system of colliding bodies, total momentum is conserved. Therefore, the total momentum of the car and dumpster after collision is 10800 kg m/s.
There is no direct relationship between power
and either of those quantities.
Answer:
D
Explanation:
5 Km=5000m
so Δv=5000 m/sec
a=Δv/Δt
=5000/10
a=500 m/sec² as 500÷1000=0.5 Km
a=0.5 km/sec²
so D is the right answer.
