= 5000 N x 3000 m
= 15 000 000 J
4. Work= F x D
Distance= W ÷ F
= 20 000 J ÷ 340 N
= 58.82 m
6. Mass= 100 kg
Distance= 60 m
Work= 1000 N x 60 m
= 60 000 J
8. Distance= 0.8 m
Mass= 62 kg
Work= F x D
= 620 N x 0.8 m
= 496 J
10. Force= 300 N
Distance= 750 m
Work=?
(a) Friction=200N (b) Friction= 300N
W= (F1-F2) x d W= (F1-F2) x d
= (300N-200N) x 750 m = (300N-300N) x 750 m
= 75 000 J / 75 kJ = 0 J
