Two watermelons fall off a kitchen counter. The masses and speeds of the fruits are in the table. How do the kinetic and/or the potential energies of
the fruits compare?(1 point)
Both fruits have only potential energy and no kinetic energy.
The watermelon B has more kinetic energy.
The watermelon A has more kinetic energy.
Both fruits have the same kinetic and potential energy
The kinetic energy of an object is defined as the energy it possesses due to its motion. The formula for calculating kinetic energy is KE = (1/2) * mass * velocity^2.
The potential energy of an object is the energy it possesses due to its position or height from the ground. The formula for calculating potential energy is PE = mass * gravitational acceleration * height.
To compare the kinetic and potential energies of the two falling watermelons, we need to consider their masses and speeds as provided in the table. However, since the table is not mentioned, let's assume that the height of the kitchen counter is zero for simplicity.
Given the mass and speed of each watermelon, we can calculate their respective kinetic energies. The watermelon with a larger mass or higher speed will have a greater kinetic energy.
To compare potential energies, we need to consider the height from which the watermelons fell. Since the height of the kitchen counter is assumed to be zero, both watermelons will have the same potential energy if they fall from the same position. However, if one watermelon was placed on a higher shelf and fell from a greater height, it would have a higher potential energy compared to the other watermelon.
In summary, the comparison of kinetic and potential energies depends on factors such as the masses, speeds, and heights from which the watermelons fell. Without specific values or additional information from the table, it is not possible to provide a definitive comparison.
