Two horizontal forces are being applied to a 6 kg object. One force has a magnitude of 10 N and is directed toward the north. the second force has a magnitude of 15 N and is directed toward the northwest. The angle between the two forces is 45 degrees.
A) Calculate the magnitude of the resultant force, R.
B) Calculate the magnitude of the acceleration of the 6 kg object.
C) Find the angle between the acceleration and the north-south axis.
