a = 1*100 = 100 Ns
b = 10 * 12 = 120 Ns
c = 0.5*1000 = 500 Ns
d = 100 * 2 = 200 Ns

a has least momentum

The object with least momentum is required.

Object a. has the least momentum.

Momentum is given by the product of mass and velocity of an object.

m = Mass = 1 kg

v = Velocity = 100 m/s

[tex]p=mv\\\Rightarrow p=1\times 100\\\Rightarrow p=100\ \text{kg m/s}[/tex]

m = 10 kg

v = 12 m/s

[tex]p=10\times 12\\\Rightarrow p=120\ \text{kg m/s}[/tex]

m = 0.5 kg

v = 1000 m/s

[tex]p=0.5\times 1000\\\Rightarrow p=500\ \text{kg m/s}[/tex]

m = 100 kg

v = 2 m/s

[tex]p=100\times 2\\\Rightarrow p=200\ \text{kg m/s}[/tex]

Object a. has the least momentum.
