A) \[\text{2}\times \text{1}{{0}^{\text{5}}}\text{ kg m}/\text{s}\]
B) \[\text{1}\times \text{1}{{0}^{8}}\text{ kg m}/\text{s}\]
C) 4 kg m/s
D) None of these
Correct Answer: A
Solution :
Momentum is defined as product of mass and velocity. Therefore p = mv Given, m = 10,000 kg, v = 20m/s \[\therefore \] \[p=10,00\times 20\] \[=2\times {{10}^{5}}kg-m/s\]
