The diagram below shows a block of mass m=2.0 kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.0 N, F2=6.0 N, and F3=8.0 N are applied to the block, initially at rest on the surface, at angles 25 degrees and 325 degrees shown on the diagram. In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis Calculate the magnitude of the total resultant force Fr=F1 + F2 + F3 acting on the mass. What angle does Fr make with the positive x axis?What is the magnitude of the mass's acceleration vector, a?What is the direction of a? In other words, what angle does this vector make with respect to the positive x axis?How far (in meters) will the mass move in 5.0 s?What is the magnitude of the velocity vector of the block at t=5.0s?In what direction is the mass moving at time t=5.0s? That is, what angle does the velocity vector make with respect to the positive x axis?
