A glider is an aircraft with no engine. To be launched, a glider is uniformly accelerated from rest by a cable pulled by a motor that exerts a horizontal force on the glider throughout the launch.

Figure for Question S1.3.2—Vectors and diagrams question 1 — IB Physics SL

At a particular instant in the flight the glider is losing 1.00 m of vertical height for every 6.00 m that it goes forward horizontally. At this instant, the horizontal speed of the glider is $12.5 \mathrm{~m} \mathrm{~s}^{-1}$ . Calculate the velocity of the glider. Give your answer to an appropriate number of significant figures.

Quote speed and direction together, to 3 significant figures. Accept a speed and direction together; the accepted values are:
$\text{speed}=12.7\,\mathrm{m\,s^{-1}}$ $\text{direction}=9.46^{\circ}=0.165\,\mathrm{rad}\text{ below the horizontal}$ $\text{gradient}=-\frac{1}{6}$
