A 400 N student pushes a 500 N trunk a distance of 8.00 m along a straight line, by applying a constant 600 N force directed 30 degrees below the horizontal. The initial speed of the trunk is 2.00 m/s and the coefficient of kinetic friction between the trunk and the floor is 0.400. 30° 1. The work which the student does on the trunk is equal to A. 3.20 kJ. B. 2.77 kJ. C. 4.80 kJ. D. 4.16 kJ. E. 4.00 kJ. 2. The work done on the trunk by kinetic friction is equal to A. - 2.56 kJ. B. - 6.40 kJ. C. - 1.60 kJ. D. - 640 J. E. - 3.26 kJ. 3. The final kinetic energy of the trunk is equal to A. zero. B. 1.60 kJ. C. 1.70 kJ. D. 0.102 kJ. E. 4.16 kl.
