Physic Question. Im seriously stuck po here.

starting the rest, a car slides 15 m down an ice-covered road, where the friction is negligible. The speed of the car at the end of the 15 m is 3.4 m/s. Find the slope angle of the road

Answer:

 \frac{ {x { \frac{ { \frac{ \sqrt {?}^{2} {?} }{?} }^{2}  \times \frac{?}{?} }{?} }^{?}  \times \frac{?}{?} }^{2} }{?}  \times \frac{?}{?}
