Ali pushes an object with a force of 50 N directed at an angle of 60o

1.	Ali pushes an object with a force of 50 N directed at an angle of 60o below the horizontal direction. Calculate the work that Ali has done on the object if the object moves 10 m horizontally. what is the answer
Answer» Answer: We KNOW frictional FORCE f=μN where N=normal force=mg Given SLIDING frictionμ=0.25 Thus, f=0.25×50×10=125N Hence Fnet=Fapp−f=575−125=450N Also we know ForceF=ma a=50450=9m/s2

Answer:

We KNOW frictional FORCE f=μN where N=normal force=mg

Given SLIDING frictionμ=0.25

Thus, f=0.25×50×10=125N

Hence Fnet=Fapp−f=575−125=450N

Also we know ForceF=ma

a=50450=9m/s2
