Answer:
224 J
Explanation:
Step one:
given data
Force applied = 22.4 N
distance = 10 meters
<u>Required:</u>
the work done
Step two:
The expression for the work done is
WD= force*distance
substitute
WD= 22.4*10
WD= 224 J
Total distance is 28+12+34=74km=74000m.
Total time is 20+8+25 minutes=53 minutes=53×60=3180 secs.
Average speed is 74000/3180=23.27 m/s.
