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,
<span>Air resistance, also called
drag, acts upon a falling body by slowing the body down to the point
where it stops accelerating, and it falls at a constant speed, known as
the terminal velocity of a falling object. Air resistance
depends on the cross-sectional area of the object, which is why the
effect of air resistance on a large flat-surfaced object is much greater
than on a small, stream-lined object.</span>
This question is personal preference... just answer with whatever YOU think, there probably isn’t s wrong answer if I’d guess.
Answer:
Fish will appear at distance 14.9 cm from the surface of bowl
Explanation:
As we know that fish is floating inside the water in fish bowl while it is observed from outside in air
so we have
here we have
now we have
