momentum = mass*velocity
which one is larger?
which one is larger?
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.
