Thank you

for Q15

final k.e - initial k.e = total work done

First situation,

8-4=Fs
4=Fs

second situation we have to find final k.e

final k.e - initial k.e =word done
final k.e -4 = 2F2s
final k.e -4 =4Fs

we know from first situatation that Fs =4

final k.e -4= 4(4)
final k.e = 16+4
final k.e = 20

so answer is B
