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

the answer is a. hope this .

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
