Answer:
The speed of rabbit is 5.73 m/s.
Explanation:
Given that,
Mass of rabbit = 5.0 kg
Mass of Irish setter = 12 kg
Speed of setter = 3.7 m/s
Both have the same kinetic energy.
We need to calculate the speed of rabbit
Using formula of kinetic energy
Put the value into the formula
Hence, The speed of rabbit is 5.73 m/s.
20m/s
Speed = distance / time
Speed = 400/20
Speed = 20
