A pendulum is probably the most common showing of this example. As the pendulum swings down, it converts its potential energy (height) into kinetic energy (velocity). At the lowest point the kinetic energy is the highest and the potential is the lowest. At the highest point in its swing the velocity is zero so the kinetic energy is zero and the potential energy is at a maximum (greatest height).
<span>15 m/s^2
The first thing to calculate is the difference between the final and initial velocities. So
180 m/s - 120 m/s = 60 m/s
So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving
60 m/s / 4.0 s = 15.0 m/s^2
Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2</span>
Parallel has more than one circuit or form of energy
series has only one form of energy circuit
Answer:
V = E * d
E = (200 J/C) / .024 m = 8330 J / C-m
1/2 m v^2 = V q potential energy of electron
v^2 = 2 * 200 J/C * 1.6E-19 C / 9.11 E-31 kg
v^2 = 400 * 1.6E-19 / 9.11 E-31 N-m / kg
v = 8.4E6 m/s
