The diagram below shows a block of mass on a frictionlesshorizontal surface, as seen from above. Three forces of magnitudes,F1=4N angle 25,F2=6N 180,F3=8N 325 are applied to the block,initially at rest on the surface, at angles given. In this problem,you will determine the resultant (total) force vector from thecombination of the three individual force vectors. All anglesshould be measured counterclockwise from the positive x axis (i.e.,all angles are positive).
Calculatemagnitude of resultant force acting on block , Fr =F1 + F2 +F3
What angle does Fr make with positive x axis
What angle does make with the positive x axis?
What is the magnitude of the mass's acceleration vector, ?
What is the direction of ? In other words, what angle does thisvector 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? In what direction is the mass moving at time ? That is, what angledoes the velocity vector make with respect to the positive xaxis?
