omg, i got it! no net force, he just need to apply additional force of 449 N to overcome friction and move it at a constant speed. Multiply this force and velocity will give me the Power ! thanks :D
Thanks for the heads up, i didn't multiply with gravity as i should have - the friction force corrected is 750.5N
I think the parallel and net forces also play a role here in resisting friction. I can't seem to get the applied force down the inclined plane.
the parallel force along the...
Homework Statement
please advise how to solve. seems i can't without d given, or t!
a man drags a 130 kg object down an inclined plane at a speed of 1.40m/s
The coefficient of friction between the object and the inclined plane is 0.800 and the angle of inclination with the horizontal is...
