At which two points will the kinetic energy of the block be the same? a and b a and c b and d b and c

B and D

Explanation:

I included the picture associated with the problem below:

Seeing as B and D are at the same level here, they posses the same amounts of kinetic energy. Another pair that would be correct, although it is not a choice, is A and E. This is because they too have the same kinetic energy (0J because they are stationary). Hope this helps! :)
