Two forces are applied to a block of mass M = 14.0 kg that sits on a horizontal, frictionless table. One force Fs 1 has a magnitude of 10.0 N and is directed at an angle u1 equal to 37.0° from the x direction as labelled in Figure 4-27. As a result of the forces, the block experiences an acceleration an equal to 0.500 m>s2 in the x direction only. (a) What are the x and y components of the second force?
