Question

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 1

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 2

Answer:

90
