Answer:
10.1 m /s²
Explanation:
Let m₁ be the mass of the helium gas inside balloon. Mass of air displaced is m₂
m₁ = volume x density
= 4/3 x 3.14 x 5³ x .179
= 93.67 kg
mass of displaced air
= 4/3 x 3.14 x 5³ x 1.16
= 607.06 kg
Net buoyant force in upward direction
(607.06 - 93.67 ) x g
= 5031.22 N
weight of people and gondola
= (2 x 70 + 64 ) x 9.8
= 1999.2 N
Net force in upward direction
= 5031.22 - 1999.2
= 3032.02 N
Acceleration produced
= 3032.02 / total mass
= 3032.02 / ( 93.67 +204 )
= 3032.02 / 297.67
= 10.1 m /s²
If you are talking about gravitational potential energy, then the ONLY way to either increase OR decrease it is to raise or lower your height. The higher you are off the ground the greater your PE, the closer you are to the ground, the lower your PE
The answer is d, gravity is the only force acting on the object
