Explanation / Answer

a) S1 = from 0.0 up to 2.0 m , F1 = 4.0 N and W1 = F1*S1 = 4*2 = 8.0 joule
S2 = from 2.0 up to 3.0 m , F2 = 6.0 N and W2 = F2*S2 = 6*1 = 6.0 joule

S3 = from 3 to 4.3 m w3 = f3*s3 = 8*1.3 = 10.4 J

Wa = W1+W2+W3 = 24.4 J

b) S4 = from 6.0 up to 9.0 m , F4 = 4.0 N and W4 = F4*S4 = 4*3 = 12.0 joule
S5 = from 9.0 up to 11.0 m , F5 = -3.0 N and W5 = F5*S5 = -3*2 = -6.0 joule

s6 = 11 to 13.5 m    w6 = -6*2.5 = -15 J

Wb = W4+W5+W6 =-9 J

c) s7 = 14 to 16m     w7 = 2*2 = 4 J

s8 = 16 to 16.7 m w8 = -2*0.7 = -1.4 J

wc = w7+w8 = 2.6 J
