Answer:
First object has greater magnitude of momentum.
Explanation:
Given that,
Speed of first object = v
Mass of first object = 2m
Speed of second object = 2√v
Mass of second object = m
Suppose we find which object has the larger magnitude of its momentum
We need to calculate the momentum of first object
Using formula of momentum
Where, m = mass of first object
v = speed of first object
Put the value into the formula
...(I)
We need to calculate the momentum of second object
Using formula of momentum
Where, m = mass of second object
v = speed of second object
Put the value into the formula
....(II)
On comparing equation (I) and (II)
Hence, First object has greater magnitude of momentum.
