Using data from Rory Young's answer: yes, a lion definitely can jump 10+ meters.
The horizontal distance D of a projectile with speed V, launched at an angle is:
Which gives, for a lion running at 54km/sec, i.e. V=15 m/s, jumping at an angle of 45 degrees, and assuming
Considering that running at maximum speed and jumping at 45 degrees is very hard, even for a lion, this is an over-estimation. But jumping at 15 degrees would allow the lion to fly over a distance D:
In addition, if a dog can jump 29 feet (9m), clearly a lion can do better....
