A rocket fires two engines simultaneously. One produces a
thrust of 755 directly forward while the other gives a thrust of 525 at an
angle 24.2above the forward direction. The resultant force can be solve using cosine
law where the angle c = 180-24.2 = 155.8. the resultant force is 1252.49. the
direction of the resultant force can be solved using sine law which is equal to
9.89 degree above the forward direction.
