Answer:
C
Explanation:
they are still in the same plane witch means they going the same speed
Well, the Train will have no movement since it is not moving, so a Sports car that is going 100 mph will have Momentum.
M = 150 kg.
Final velocity, v = 14 m/s
Initial Velocity, u = 6 m/s
Impulse = <span> m(v - u)</span>
= 150*(14 - 6)
= 150*8 = 1200 kgm/s or 1200 Ns<span> </span>
Answer: Energy cannot be <u>created</u> or <u>destroyed</u> just <u>changes</u> in form.
Explanation:
This is the principle of the first Law of Thermodynamics, which relates the work and the transferred energy exchanged in a system through the internal energy, which is neither created nor destroyed, it is only transformed.
In other words: The total energy of a system is always conserved.
Most likely, the equation is
<em>Acceleration over a period of time = </em>
<em>(change in speed during the period of time)</em>
<em>divided by</em>
<em>(length of the period of time) .</em>
for any piece of the graph.
