Answer:

99J

Explanation:

distance s = 3 m

The force is given at an angle .Cos it to get horizontal and sin it get vertical

force f  horiz = 55N * cos 35 = 45 N

angle is 35

Friction F = 12N

we need to take resultant force as work is done after every force does its contribution.We sub pulling with friction to get resultant

W= (f-F) S

W= 45-12 * 3

W= 33*3

W= 99J
