As the velocity is constant so acceleration of the object is supposed to be zero
ma= F1+F2+F3
0= 2. 9i + 2.2j - 2k - 5.1i + 3.4j - 1.6k + F3
F3= 2.2i - 5.6j + 3.6k

The figure shows an overhead view of a 0.028 kg lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force F 1 has a magnitude of 3 N and is at θ1-26. Force F2 has a magnitude of 6 N and is at θ2-34°. In unit-vector 2(i-3) notation, what is the third force if the lemon half (a) is stationary, (b) has the constant velocity v = 12,-12) m/s,...
Consider a bar, of length 5.5 m, shown in the figure, being acted on by three forces. The magnitudes of the first two forces are 16 N and 29 N, and the first force is acting on the end of the bar at an angle of 29° as shown. Part (a) What is the torque, in newton-meters, due to F1 on this bar relative to the left end? Use a coordinate system with positive directed out of the screen. Part (b) What...
- Two forces, F1 = (3.80î − 2.80ĵ) N and F2 = (4.90î – 8.15ĵ) N, act on a particle of mass 2.20 kg that is initially at rest at coordinates (+1.60 m, -3.90 m). What are the components of the particle's velocity at t = 10.7 s? In what direction is the particle moving at t = 10.7 s? What displacement does the particle undergo during the first 10.7 s?

Three forces acting on an object are given by # = (-2.21 + 7.155) N, F2 = (4.559 – 2.55) N, and F3 = (-49.51) n. The object experiences an acceleration of magnitude 3.95 m/s2 (a) What is the direction of the acceleration? 5.6 x Note that the direction of the acceleration is the same as the direction of the net force. (counterclockwise from the +x-axis) (b) What is the mass of the object? 12.0 kg (c) If the object...
Three forces act on a moving object. One force has a magnitude of 78.6 N and is directed due north. Another has a magnitude of 55.3 N and is directed due west. What must be (a) the magnitude and (b) the direction of the third force, such that the object continues to move with a constant velocity? Express your answer as a positive angle south of east.
