Answer:
Explanation:
m = Mass of initial piece = 1.2 kg
= Velocity of toy in x direction = 0.05 m/s
= Velocity of toy in y direction = 0
= Velocity of fragment 1 in x direction = 0
= Velocity of fragment 1 in y direction = -0.9 m/s
= Velocity of fragment 2 in x direction
= Velocity of fragment 2 in y direction
= Mass of fragment 1 = 0.4 kg
= Mass of fragment 2 = 1.2-0.4 = 0.8 kg
Applying conservation of momentum in x axis
Applying conservation of momentum in y axis
From the above two final equations we get
The direction of the fragment 2 is
The velocity of fragment 2 is
