Create a Vector named a_force that represents acceleration due to a force of 0.5 Newton applied to an object with mass 0.3 kilograms, in a direction 45 ° up from the positive x-axis.

Add a_force to a_drag from the previous exercise. If that addition succeeds, that means that the units are compatible. Confirm that the total acceleration seems to make sense.
