Question

The diagram below shows an object of mass m= 20kg being acted upon by a force F=50N at an angle of θ=30o. The coefficient of kinetic friction between the object and the surface is 0.100.

 

a.Draw a Free Body diagram for the object.  Be sure to show all forces as well as the reference x,y axis. and        Using Newton’s 2nd law, write the force equations for both the x and the y directions.  Write these equations in terms of the letters  m, F, θ, FN, g, f (little f stands for the friction force).

 

                X-direction: _______________________________________________________________

 

                Y-direction:________________________________________________________________

 

b.Solve for the Normal Force                         

 

 

 

 

c .Use your answer from part b to find the frictional force.

 

 

 

 

d .Solve for the acceleration of the object.

 

       

 

 

e.If this object was originally moving at 4 m/s, how fast would it be moving after 8 seconds?

 

 

 

 

f .How far will it have moved after 8 seconds?

Please answer the following d), e) and f). Full question is provided for convenience.
