A5 kg shell at rest, suddenly splits up into
three parts. If two parts with 2 kg each are
found flying due north and east at 5 m/s
velocity each, the velocity of the third part just
after the explosion is​

Answer 1

Answer:

The velocity of third part after explosion is v_{3}= 10\sqrt{2}m/sv

3

=10

2

m/s .

Explanation:

Given that,

Mass of first part m_{1} = 2 kgm

1

=2kg

Mass of second part m_{2} = 2 kgm

2

=2kg

Initial velocity u = 0

Velocity of first and second part after explosion v = 5 m/s

Using conservation of momentum

mu= m_{1}v_{1}+m_{2}v_{2}+m_{3}v_{3}mu=m
