Under the action of two mutually perpendicular forces F1 = 6N and F2 = 8N, the object moves 10m along the direction of their resultant force 1. How much work does the force F1 and F2 do to the object? 2. How much work does their resultant force do to the object?

W1=F1*S1=6*10*sin36.8°=6*6=36J
W2=F2*S2=8*10*cos36.8°=8*8=64J
W combination = f combination * s = 10 * 10 = 100J (or W combination = W1 + W2 = 100J, the addition of work follows scalar addition)
