The largest hydraulic turbines in the world have shafts with individual masses that equal 3.18x10^5 kg. Suppose such a shaft is delivered to the assembly line on a trailer that is pulled with a horizontal force of 81.0kN. If the force of friction opposing the motion is 62.0kN, what is the magnitude of the trailer's net acceleration? (disregard the mass of the trailer.)

Question

anonymous · Answer

F=MA
Fnet=F applied - F friction 
MA =F applied - F friction   solve for A=?
