[1 point, 10 tries] A 16.0 kg block is dragged over a rough, horizontal surface by a 69.5 N force acting at 19.9 degrees above the horizontal. The block is displaced 5.17 m, and the coefficient of kinetic friction is 0.308. Find the work done by the 69.5 N force. Answer: 3.38e+02 J 2 . [1 point, 10 tries] Find the work done by the normal force. Answer: 0 J 3 . [1 point, 10 tries] What work does the gravitational force do on the block? Answer: 0 J 4 . [1 point, 10 tries] How much energy is lost due to friction? Answer: 2.12e+02 J 5 . [1 point, 10 tries] Find the total change in the block's kinetic energy. Answer: 1.26e+02 J 6 . [1 point, 10 tries] Calculate the scalar product of the vectors in the figure below.
