Which would have a greater momentum: a lion with a mass of 150kg travelling at a speed of 72km hr or a 1200 kg safari car travelling at 6.0km hr?

momentum = mass*velocity

which one is larger?

To compare the momenta of the lion and the safari car, we need to remember the formula for momentum:

Momentum = mass 脳 velocity

First, let's convert the lion's speed from km/hr to m/s, since the unit of momentum is kg路m/s. To do this, we divide the speed by 3.6:

72 km/hr 梅 3.6 = 20 m/s

Now, let's calculate the momentum of the lion:

Momentum = mass 脳 velocity
= 150 kg 脳 20 m/s
= 3000 kg路m/s

Next, let's convert the safari car's speed:

6.0 km/hr 梅 3.6 = 1.67 m/s (approx.)

Now, we'll calculate the momentum of the safari car:

Momentum = mass 脳 velocity
= 1200 kg 脳 1.67 m/s
= 2004 kg路m/s

Comparing the two, we can see that the lion has a greater momentum:

Lion: 3000 kg路m/s
Safari Car: 2004 kg路m/s

Therefore, the lion has a greater momentum compared to the safari car.
