Question

Lions can run at speeds up to approximately 80.0 km/h. A hungry 110 kg lion running northward at top speed attacks and holds onto a 36.0 kg Thomson's gazelle running eastward at 75.0 km/h Find the final speed v of the lion-gazelle system just after the lion attacks m/s Find the angle 0 between the final velocity of the lion-gazelle system and the East axis, with positive angles measured counterclockwise from the East axis

I got 17.51 for the first answer but it's telling me that it's wrong. Can anyone help me, please?

Answer 1

hi - 12025 ー109.65 bn/hr 75 15 ST R. V10 36

the answer is one of this.please go through the concept .the second one is through the conservation of momentum concept that is

let the mass of lion is M and mass of gazelle is m then

Mx80+mx75=(M+m)v

the velocity after the collision is the same because after collision they are a single mass that is a single unit.

if any doubt, please ask me in the comment section
