Assume that you have an 18 kg object with the following forces acting on it. The object is initially at rest, and the coefficients of friction are =0.25 and =0.22 A. Describe each force in component form using , unit vectors, for example a vector that has a component of 12 units in x direction and 6 units in the y direction can be written as 12 6 . This will allow you to make an equation for Newton's Second Law for each direction. Don't forget that direction matters, left is negative, and right is positive. Also, as friction depends on the normal force you can skip this force and the normal force as you will calculate them later. Freebie, this is how you should write your vectors, below is the vector that describes gravity. 0?176 B. Whats the equation using Newton's Second Law for the y-direction. C. Using the equation written for Newton's Laws in the y-direction solve for the normal force. (Check your answer the value to the solution should be between 120N and 180N) D. Calculate the force due to static friction E. Will this object move? Explain how you can figure this out? F. Whats the equation for Newton's 2nd Law for the x-direction and solve the acceleration ??. Don't forget once the object is moving you need to consider kinetic friction and not static friction G. How much time will it take for this object to travel 32 m?
