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)
Use the table of information to answer the question (Watermelon A) (Watermelon B) Mass (kg) (4, 4) Speed (m/s) 2 and 4
The kinetic energy of an object is given by the formula KE = 0.5mv^2, where m is the mass and v is the speed of the object.
For Watermelon A:
KE = 0.5 * 4 * 2^2 = 8 J
For Watermelon B:
KE = 0.5 * 4 * 4^2 = 32 J
Therefore, the kinetic energy of Watermelon B is 4 times greater than that of Watermelon A.
The potential energy of an object is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity (9.81 m/s^2), and h is the height of the object.
Since both watermelons fall off the same height (kitchen counter), their potential energies will be the same.
In conclusion, the kinetic energy of Watermelon B is 4 times greater than that of Watermelon A, while their potential energies are equal.
