Answer 1

Answer:this is ur answer

Explanation:

Answer 2

Explanation:

For this we apply

m1v1 + m2v2 + m3v3 = 0

here

m1 = 10g = 0.01kg

v1 = 30 m/s

m2 = 20g = 0.02kg

v2 = 20 m/s

m3 = 30 g = 0.03 kg

v3 = ??

now there are also directions so

it will be

0.03×v3 = - ( 0.01×30i + 0.02×20j)

v3 = -1( 30i + 40j )/3

v3 = - 50/3 m/s
