Ahot air balloon lifts a gondola full of people off the ground. what is the mass of the gondola if the force on the balloon is 1200 n and it has an upward acceleration of 2.4 m/s2 ? a 51.0 kg b 98.4 kg c 162.2 kg d 293.9 kg

The correct answer is C.

Explanation:

Given, net force, F = 1200 N

Upward acceleration = 2.4 m/s²

Downward acceleration= Acceleration due to gravity= 9.8 m/s²

Net acceleration, a= 9.8-2.4 = 7.4 m/s²

Force on an object of mass m is given by relation,

F= ma

∴ Mass of the gondola =

Substituting the values,

M=

=162.2 kg

this would be about 43%
