Shown below is a 45 kg crate that is pushed at constant velocity a distance 8.1 m up a 30° incline by the horizontal force F. The coefficient of kinetic friction between the crate and the incline is u 0.49. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) 45 kg 30° (a) Calculate the work done (in J) by the applied force. 3816.572388 J (b) Calculate the work done (in J) by the frictional force -1517.37614 X J (c) Calculate the work done (in J) by the gravitational force. -1787.8725 (d) Calculate the work done (in J) by the net force. 5048.850699 J LL
