two horizontal forces F1 and F2, acting on an object of mass 1.11kg. The magnitude of F1 is 27.56N. The object moves strictly along the horizontal x-axis, which we choose as positive to the right. Find the magnitude of F2 if the object has a horizontal acceleration of 8.4m/s^2.


b). What is the magnitude of F2 if the object has a horizontal acceleration of 0m/s^2?

c). What is the magnitude of F2 if the object has a horizontal acceleration of -9.30m/s^2?

    (a) ma=F1+F2 =0
    F2=F1 = 27.56 N
    (b)ma=F1+F2
    1.11•(-9.3) = 27.56 +F2
    F2= -37.883 N

    for b, switch the negative to positive. F2 is in the negative direction so the negative on your answer and the negative on F2 cancel
