kumpel [21]

<h3>Answer : 360J</h3>

s = 40m - 4m = 36m

W = F × s

= 10N × 36m = 360J

Elina [12.6K]

Answer: 10.67

Explanation:

First, we needed to calculate the radius and this will be:

= Diameter / 2

= 0.900km / 2

= 0.450km

Since s = 3.00miles, we need to convert it to kilometers and this will be:

1mile = 1.6km

3 miles = 3 × 1.6km = 4.8km

Radians = s/r = 4.8/0.45 = 10.67
