In a contest, two tractors pull two identical blocks of stone thesame distance over identical surfaces. However, block A is moving twice as fast as block B when it crosses the finish line. Which statement is correct?a) Block A has twiceas much kinetic energy as block B. b) Block B has losttwice as much kinetic energy to friction as block A. c) Block B has losttwice as much kinetic energy as block A. d) Both blocks havehad equal losses of energy to friction. e) No energy is lostto friction because the ground has no displacement.

d) Both blocks have had equal losses of energy to friction

Explanation:

As it is mentioned in the question that two tractors pull two same stone blocks having the identical distance over the same surfaces

Moreover, the block A is twice as fast than block B at the time of crossing the finish line

So based on the above information,  it contains the losses of identical friction

And we also know that

Friction energy loss is

It would be the same for both the blocks

hence, the option d is correct

explanation:

the masses of the objects and the distance between them
