Answer:

1168.05 J

Step-by-step explanation:

The work that the boy does can be calculated as

W = Fdcosθ

Where F is the force, d is the distance and θ is the angle. Replacing F = 41.5 N, d = 32.5 m, and θ = 30 degrees, we get:

W = (41.5 N)(32.5 m)cos(30)

W = 1168.05 J

Therefore, the answer is 1168.05 J
