Answer :
Answer: 739.3 J
Explanation: To find the work done by the boy, you need to use the formula:
W = F × d × cos(θ)
Where W is the work done, F is the force exerted by the boy (205 N), d is the distance traveled by the wagon (35.0 m), and θ is the angle between the force and the direction of motion (22.0 degrees).
First, you need to convert the angle from degrees to radians:
22.0 degrees × (π/180) = 0.384 radians
Now, plug in the values:
W = 205 N × 35.0 m × cos(0.384 rad)
= 205 N × 35.0 m × 0.957
= 739.3 J
So, the boy does 739.3 joules of work on the wagon as he pulls it along the sidewalk.
