Suppose that your cousin exerted about 550 N net force on your his traveling bag at an
angle of 30°, resulting to a 100 m displacement, what will be the amount of work done on
the bag?

Answer:
W = 8250 J
Explanation:
W = F × D × Cosine(θ), where F = force (in newtons), D = displacement (in meters), and θ = the angle between the force vector and the direction of motion.
W = 550 N × 100 m × cos (30°)
W = 550 N × 100 m × 0.15
W = 55 000 N × 0.15
W = 8250 J
