Question

a bird lifts up with the help of the air up thrust, if the bird is moving up with acceleration of 5.3 m/s^2 and mass of the bird is 250 g find the up thrust by air?

Answer 1

Answer:

11m is the answer for this question

Explanation:

When bird moving up the acceleration then bird pushes air downward at that exert force on the cage floor. That is equal to weight =m(a+g)=m(1+g)=11m

Where, m= mass of bird.

Hence, the answer is solved.
