Two forces are applied to a block of mass M equal to 14 kg that sits on a horizontal, frictionless table. One force F1 has a magnitude of 10 N and is directed at an angle theta1 equal to 37 degrees from the x direction. As a result of the forces, the block experiences an acceration equal to .5 m/s^2 in the x direction only.
a) Find the x and y components of the second force.
b) Draw the second force in its correct position and to scale.
