Answer:
degrees
Explanation:
Eels have been recorded to spin at up to 14 revolutions per second when feeding in this way
So the angle the eel rotate is going to be
Camera record 120 frames per second
time taken for 1 frame record
eel rotates
degrees in 1 second
so:
eel rotetas degrees
The impulse is equal to the variation of momentum of the object:
where m is the mass object and
is the variation of velocity of the object.
The ball starts from rest so its initial velocity is zero:
. So we can rewrite the formula as
or
and since we know the impulse given to the ball (I=16 Ns) and its mass (m=2 kg), we can find the final velocity of the ball:
where m is the mass object and
