80m/s while a 15,000 kg truck is traveling at 20m/s Which has the greater momentum? A 300 kg snowmobile is traveling at 30m/s How fast would a 200 kg snowmobile need to travel to have the same momentum?

To determine which has the greater momentum, we use the formula for momentum
, where
is mass and
is velocity.For the 300 kg snowmobile traveling at 80 m/s:
For the 15,000 kg truck traveling at 20 m/s:
The truck has the greater momentum.Next, to find how fast a 200 kg snowmobile would need to travel to have the same momentum as the 300 kg snowmobile traveling at 30 m/s:First, calculate the momentum of the 300 kg snowmobile at 30 m/s:
Now, set this equal to the momentum of the 200 kg snowmobile and solve for its velocity
:
So, the 200 kg snowmobile would need to travel at 45 m/s to have the same momentum.
