Answer:
Speed of larger piece is
Explanation:
We apply the principle of conservation of momentum.
The watermelon is initially at rest. The initial momentum = 0 kg m/s in all directions.
After the collision,
Vertical momentum = momentum of piece in y-direction + y-component of momentum of larger piece =
Here, is the y-component of velocity of larger piece.
This is equal to 0, since the initial momentum is 0.
Horizontal momentum = momentum of piece in x-direction + x-component of momentum of larger piece =
Here, is the x-component of velocity of larger piece.
This is also equal to 0, since the initial momentum is 0.
The velocity of the larger piece, , is the resultant of
and
. Since they are mutually perpendicular,
