Question

A balloon of mass 10 kg moving upward with acceleration 20 m/s2 if mass 4 kg mass is removed by balloon so what is the acceleration of balloon

Answer 1

Answer:

follow me

Explanation:

ballon mass =10 kg

acceleration=20 m/s2

then

Answer 2

Answer:

39.873 m/s²

Explanation:

m = Mass

a = Acceleration = 20 m/s²

g = Acceleration due to gravity = 9.81 m/s²

Force exerted by the balloon

$F=m(g+a)\\\Rightarrow F=10(9.81+20)\\\Rightarrow F=298.1\ N$

Now, 4 kg is released. So, mass of the balloon is 10-4 = 6 kg

$F=m(g+a)\\\Rightarrow F=mg+ma\\\Rightarrow a=\frac{F-mg}{m}\\\Rightarrow a=\frac{298.1-6\times 9.81}{6}\\\Rightarrow a=39.873\ m/s^2$

Acceleration of the balloon is 39.873 m/s²
