A 19.2 kg block is dragged over a rough, horizontal surface by a constant force of 190 N acting at an angle of 32◦ above the horizontal. The block is displaced 68.5 m, and the coefficient of kinetic friction is 0.149. The acceleration of gravity is
9.8 m/s²
a) 1.2×10 ³ J
b) 2.4×10 ⁴ J
c) 4.8×10 ⁴ J
d) 6.4×10 ⁴ J
