Question

A balloon has mass of 5g in air. The air escapes from balloon at uniform rate with velocity 5cm/sec, if balloon shrink completely in 2.5sec. Find average force on balloon.​

Answer 1

Answer:

average force=10N

Explanation:

mass=5g,rate of velocity =5cm/sec

therefore,a=5/2.5

=5/(25/10)=5*10/25=2cm/sec2

force =m*a=5*2=10N
