Problem

A drone starts from the origin, flies

100\,\text{m}

due east, then ascends vertically

60\,\text{m}

, and finally travels

80\,\text{m}

due north. Determine the pair that best represents (magnitude of resultant displacement, angle with the horizontal plane). a)

128\text{ m},\,30^{\circ}

141\text{ m},\,25^{\circ}

117\text{ m},\,31^{\circ}

141\text{ m},\,64^{\circ}
