Question

A balloon of total mass 180 kg just floats motionless in the earth's atmosphere. If 60 kg of load in it is thrown out, with what acceleration will the balloon start to rise?
(a) 0
(b) 2 m/s^2
(c)5 m/s^2
(d) 10 m/s^2​

Answer 1

Answer:

5m/s^2 it will start to rise

Answer 2

total mass=180kg

a=?

g=10

a=N.D.F/Total mass

=180g-60g/180+60

=1800-600/240

=1200/240

=5m/s^2

hope it helps u☺️
