In a contest, two tractors pull two identical blocks of stone the same distance over identical surfaces. However, block A is mo twice as fast as block B when it crosses the finish line. Which statement is correct? A Block A has twice as much kinetic energy as block B. 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.

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? A Block A has twice as much kinetic energy as block B. 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. D Both blocks have had equal losses of energy to friction. (E No energy is lost to friction because the ground has no displacement.
