here the net force of the system is ma take the forces, -------->u have the applied force...(43N) and the force against it which u don't have (Ff) and equate it to the net force so, ma = Fapplied - Ffriction i thinks that's how u solve it...i can be wrong... once you solve for friction...

Homework Statement A weight, mass m = 80 kg , is pulled over a rough horizontal plane, mu = 0.15, by a force of magnitude F = 359 N, making an angle of 43 degrees with the plane, away from the plane. Calculate the speed of the weight d= 1.5 m away from its initial position assuming that it...

i have a similar problem...anyone help?

Homework Statement A tugboat releases a barge and continues down the river for t = 64 min. Then it returns and finds the barge 3.9 km downstream from its initial position. Assuming that the speed of the tugboat was constant with respect to the water, the speed of the river is (in km/h)...
