Question

A helium balloon can just lift a load of 780 N. The skin of the balloon has a mass of1.0 kg. (a) What is the volume of the balloon?
1 m3

(b) If the volume of the balloon were twice that found in part (a),what would be the initial acceleration of the balloon when itcarried a load of 1000 N?
2m/s2 (a) What is the volume of the balloon?
1 m3

(b) If the volume of the balloon were twice that found in part (a),what would be the initial acceleration of the balloon when itcarried a load of 1000 N?
2m/s2

Explanation / Answer

       a)              = mass / volume                   volume = m /    volume of theballon    V      = 1 /0.1786                                               = 5.599 m3        b)Gi8ven   force F = 1000 N                          mass of the ballon = 1 kg                          vlume of the ballon = 5.599 m3                  F = m a                   mass = volume x density               so F = V x x a                  a = F / V                                 plugthe values and get the answere
