In the previous problem `3` the magnitude of the momentum transferred during the hit is .

Options

A. zero
B. `0.75 kgms^(-1)`
C. `1.5kgms^(-1)`
D. `14kg ms^(-1)`

Answer

c

Explanation

Magnitude of momentum transferred (=change in momentum) `|vec(p)| = sqrt(0.9^(2) + (1.2)^(2)) = 1.5kgms^(-1)` .
