Three forces act simultaneously on a 2.70-kg block. For clarity the drawings show the forces separately. The block starts from rest and, as a result of the combined action of the forces, undergoes a displacement s, which has a magnitude of 6.50 m. What is the final speed of the block?
First image: angle 38 degrees, F=75N
Second: 54N= Horizontal force
Third: angle 65, F=93N
