2000
Ns−1
Step-by-step explanation:
If we look at the equation for momentum:
p=mv p=momentum in Newton meter-
Ns−1
m= mass of the bicycle in kg
v =velocity of the bicycle in meters per second - ms−1
Now, we only really have access to the momentum and not the velocity or the mass of the bicycle. Not to worry! We can still make a comparison between the two scenarios.
In the first case:
1000=mv
In the second case:
p=m×2v
Hence p=2mv
Now we can see that in the first case we have mv
momentum, while in the second case we have 2mv momentum- we have twice as much momentum in the second case!
So the momentum in the second scenario must be double of what it was in the first scenario:
2000 N s−1
This can also be deduced from the formula: as the formula for momentum is based on the product of the mass and the velocity. Hence if you double either of them, the momentum will double. Or if you double both, the momentum will quadruple.
