A trunk of mass m = 1.600 kg is pushed a distance d = 145 cm up an incline with an angle of inclination theta = 35.0 ° by a constant horizontal force P = 450. N The coefficient of kinetic friction between the trunk and the incline is 0.210. Calculate the work done on the trunk by the applied force P. (I've done this so many times and I cant figure out what I am doing wrong? I feel like I understand it though.) Please help.
