Homework Help: physics

Posted by jr on Wednesday, January 26, 2011 at 4:05pm.

Figure shows an overhead view of a 0.026 kg lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force F1 has a magnitude of 4 N and is at еш1 = 27вк. Force F2 has a magnitude of 6 N and is at еш2 = 25вк. If the lemon half is stationary, what are projections of the third force on (a)x-axis, (b)y-axis? If the lemon half has constant velocity v = (12 i - 14 j) m/s, what are projections of the third force on (c)x-axis, (d)y-axis? If the lemon half has varying velocity v = (11ti - 13tj) m/s2, where t is time, what are projections of the third force on (e)x-axis, (f)y-axis?
