What A Drag?

[bhavanam]

I drag a mass m=21 kg in a straight line, along a horizontal surface, a distance D=23 m . I drag it at constant speed v=0.90 m.s−1 in a straight line using a horizontal force. The coefficients of friction are k1= 1.2μ
k2 = 1.1μ
k
​ =1.1. How much work do I do? W = ____ J .

Work it out yourself, we are not here to do your homework for you!

[fiction-factory]

Tell us which equations you think might be relevant here. For example don't key words in you make you think of an equation which covers force, distance and work. Then think how to build in the friction factor (no, not me)

I'm not sure why I'm bothering though as you never acknowledged the contributions we made to all your other threads

"How much work do I do?" Not enough?
