Explanation:
From the question we are told that
The radius of the spherical balloon is
The mass of the balloon is
The volume of the spherical balloon is mathematically represented as
substituting values
The total mass the balloon can lift is mathematically represented as
where is the density of helium with a value of
and is the density of air with a value of
substituting values
Now the mass of the cargo is mathematically evaluated as
Answer:
51.94 ft/s²
257.63 ft/s
Explanation:
t = Time taken = 4 s
u = Initial velocity = 34 mi/h
v = Final velocity
s = Displacement = 615 ft
a = Acceleration
Converting velocity to ft/s
Equation of motion
Acceleration is 51.94 ft/s²
Final velocity at this time is 257.63 ft/s
