A 80 kg base runner begins his slide into second base while moving at a speed of 4.53 m/s. the coefficient of friction between his clothes and earth is 0.674. he slides so that his speed is zero just as he reaches the base. the acceleration of gravity is 9.8 m/s². what is the magnitude of the mechanical energy lost due to friction?
A) 1.32 kJ
B) 1.68 kJ
C) 2.05 kJ
D) 2.33 kJ
