Answer :
Final answer:
The elephant has a larger magnitude of momentum.
Explanation:
The magnitude of momentum depends on both the mass and velocity of an object. In this case, we have a 3000-kg elephant moving at 40 km/h and a 60-kg cheetah moving at 112 km/h. To determine which has a larger magnitude of momentum, we need to calculate their momenta.
The momentum of an object is given by the formula: momentum = mass * velocity.
Let's calculate the momentum of the elephant first:
Elephant's momentum = 3000 kg * (40 km/h * 1000 m/km)/(3600 s/h) = 333,333.33 kg·m/s
Now, let's calculate the momentum of the cheetah:
Cheetah's momentum = 60 kg * (112 km/h * 1000 m/km)/(3600 s/h) = 186.67 kg·m/s
Comparing the two results, we can see that the elephant has a larger magnitude of momentum. Therefore, the answer is A) Elephant.
