As, per the buoyancy force,the volume that the balloon should have is 2863
What is buoyancy force?
Air buoyancy is the upward force exerted on an object by the air that is displaced by object. Air buoyancy is responsible for the buoyancy created by the displaced air.
= -Vρg , where V= volume of the object
ρ = density of the object
g = acceleration due to gravity
= buoyant force
The buoyancy force must be equal to the total load lifted
ρ × V × g + 269 + 2910 = ρ × V × g
0.179 × V + 3179 = 1.29 V
0.179V + 3179 = 1.29V
0.179V- 1.29V = - 3179
1.11V = 3179
On solving , we get
V = 2863
Therefore, the volume that the balloon should have is 2863.

The acceleration is zero when the slope of a velocity Vs time graph is zero. Therefore at 2sec the slope is zero and acceleration is zero.
So the answer is D. T=2sec
