it would be 5,400n. i hope this !
in this question, we have given,
we will first calculate displacement of jetliner when speed is constant
from second equation of motion we know that,
now calculate displacement s' when it is decelerating
therefore total displacement=s+s'
the final velocity of the skateboarder is 23.75 m/s.
we can use conservation of momentum to calculate the magnitude of the final velocity.
momentum before collision is equal to the momentum after collision
here, v is final velocity of the skateboarder, assuming right side velocity as positive, and left side velocity as negative.
here, negative sign indicates that both skyboarder and bus will move in left direction.
