Two identical cars are driving in opposite directions at the same speed. their kinetic energies have . different magnitudes and opposite signsb. different magnitudes, but the same signc. the same magnitude and signd. the same magnitude, but opposite signs

The kinetic energies have the same magnitudes and signs. (c)

Why?

To answer the question, we need to remember the equation to calculate the kinetic energy of a body.

From the equation, we can see that no matter the direction of the movement, if we square the speed, we will get a positive value, so, it means that the kinetic energy will be always positive. Remember, the kinetic energy is not a vector but a scalar value.

Now, from the statement we know that both cars are identical (both have the same mass) and both are moving at the same speed, it means that the kinetic energies for the two cars will have the same magnitude and the same sign.

Have a nice day!

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong
