A child pulls a wagon 3.0 m using a force of 55 N at an angle 35° above horizontal. The force of friction on the wagon is 12 N. Calculate the net work done on the wagon

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

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
