For the block shown above, F1 has a magnitude of 15.0 N and acts at an angle of 55.0 degrees above the horizontal, and F2 has a magnitude of 30.0 N and acts at an angle of 25.0 degrees above the horizontal. If the block has a mass of 20.0 kg, find a) the normal force exerted on the block by the ground, b) the net force in the horizontal direction, and c) the displacement of the block after 5.00 seconds if the initial speed of the block was +10.0 m/s (assume to the right is +x).
