Lions can run at speeds up to approximately 80.0 km/h. A hungry106 kg lion running northward at top speed attacks and holds onto a37.5 kg Thomson's gazelle running eastward at 77.5 km/h.
Find the final speed ?f of the lion‑gazelle system just afterthe lion attacks.
Find the angle ?θ between the final velocity of the lion‑gazellesystem and the East axis, with positive angles measuredcounterclockwise from the East axis.
