To calculate the kinetic energy of a moving object, the formula is
KE = 0.5 * mass * velocity^2
Given that the kinetic energy of the car is 1,200 Joules and it is going at 28 m/s, we can rearrange the formula to solve for mass:
1,200 = 0.5 * mass * 28^2
1,200 = 0.5 * mass * 784
1,200 = 392 * mass
mass = 1,200 / 392
mass ≈ 3.06 kg
Now that we have the mass of the car, we can calculate the kinetic energy of the truck:
KE = 0.5 * 3.06 * 25^2
KE = 0.5 * 3.06 * 625
KE = 0.5 * 1,912.5
KE = 956.25 Joules
Therefore, the kinetic energy of the car is approximately 1,200 Joules and the kinetic energy of the truck is approximately 956.25 Joules.

The truck has more kinetic energy because it has a higher mass than the car even though the car is going faster. The kinetic energy depends on both speed and mass, and in this case the truck's greater mass gives it more kinetic energy.

Dam B would be able to produce more electricity because it has a greater height. The height of the dam affects the potential energy of the water stored in the reservoir behind it. The potential energy is converted into electrical energy by the hydroelectric power plant at the base of the dam. The greater the height of the dam, the more potential energy the water has, leading to a larger amount of electricity that can be generated.
