Responses
The watermelon A has more kinetic energy.
The watermelon A has more kinetic energy.
The watermelon B has more kinetic energy.
The watermelon B has more kinetic energy.
Both fruits have only potential energy and no kinetic energy.
Both fruits have only potential energy and no kinetic energy.
Both fruits have the same kinetic and potential energy.
The watermelon B has more kinetic energy.
The correct answer is: Both fruits have the same kinetic and potential energy.
To answer the question, we need to understand the concepts of kinetic and potential energy.
Kinetic energy is the energy an object possesses due to its motion, and it depends on the mass and speed of the object. The formula for kinetic energy is KE = 0.5 * mass * speed^2.
Potential energy, on the other hand, is the energy an object possesses due to its position or state. In this case, since the watermelons have fallen off a kitchen counter, they have gravitational potential energy. The formula for potential energy is PE = mass * gravity * height, where gravity is a constant (usually 9.8 m/s^2) and height is the distance of the object from a reference point (in this case, the height from the kitchen counter to the ground).
Using the table of information, we can see that both watermelons have the same mass of 4 kg. However, watermelon A has a speed of 2 m/s, while watermelon B has a speed of 4 m/s.
To compare their kinetic energy, we can use the formula KE = 0.5 * mass * speed^2. Plugging in the values for watermelon A, we get KE_A = 0.5 * 4 kg * (2 m/s)^2 = 8 J. For watermelon B, we have KE_B = 0.5 * 4 kg * (4 m/s)^2 = 32 J.
Since watermelon B has a higher kinetic energy (32 J) compared to watermelon A (8 J), we can conclude that "The watermelon B has more kinetic energy" is the correct answer.
