Braeden Atkinson · Answer 1

the angular momentum of the paticle is 8.4i - 10.2j.

Explanation:

the angular momentum is given by:

L = m*v*r

= (1.40) * (4.00i - 3.30j) * (1.50i + 2.20j)

= (1.40) * [ (4.00*1.50) i - (3.30*2.20) j]

= (1.40) * (6i - 7.26j)

= 8.4i - 10.2j

Therefore, the angular momentum of the paticle is 8.4i - 10.2j.
