An object of mass 50 g is in motion at rate of `(5hati-hatj+hatk) ms^(-1)`. Calculate the momentum involved.

Text Solution

Verified by Experts

We are given: m = `50 g = 50 xx 10^(-3) kg, vecv = (5hati-hatj+hatk) ms^(-1)`
We are to calculate: linear momentum: p
We know that `|vecv|= sqrt(5^(2)+(-1)^(2)+(1)^(2))= sqrt(27) ms^(-1)`
Using relation: `p = mv = 50 xx 10^(-3) xx sqrt(27)= 0.259 kg ms^(-1)`
