In a contest, two tractors pull two identical blocks of stone the same 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?

◦
Block A has twice as much kinetic energy as block B.

◦
Block B has lost twice as much kinetic energy to friction as block A.

◦
Block B has lost twice as much kinetic energy as block A.

◦
Both blocks have had equal losses of energy to friction.

◦
No energy is lost to friction because the ground has no displacement.
