I'll answer since there are no answers to refer to. A jovian planet is pretty much a planet that doesn't have a solid surface. It's a planet made up primarily of gases hydrogen, nitrogen, helium, methane and so on
Answer:
The mailbag will take 2.44 seconds to reach the ground.
Explanation:
The height of a helicopter above the ground is given by:
![h = 3.15\times t^3](https://tex.z-dn.net/?f=%20h%20%3D%203.15%5Ctimes%20t%5E3)
Height of helicopter at t = 2.10 seconds
![h(2.10 )=3.15\times (2.10 )^3 m=29.17 m](https://tex.z-dn.net/?f=h%282.10%20%29%3D3.15%5Ctimes%20%282.10%20%29%5E3%20m%3D29.17%20m)
The helicopter releases a small mailbag from the height of 29.17 m.
The initial velocity of mailbag = u = 0 m/s
Duration in which mailbag will reach the ground = T
Acceleration due to gravity = g = ![9.8 m/s^2](https://tex.z-dn.net/?f=9.8%20m%2Fs%5E2)
Using second equation of motion ;
![s=ut+\frac{1}{2}gt^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dgt%5E2)
We have , s = 29.17
u = 0 m/s
t = T
![29.17m=0 m/s\times T+\frac{9.8 m/s^2\times T^2}{2}](https://tex.z-dn.net/?f=29.17m%3D0%20m%2Fs%5Ctimes%20T%2B%5Cfrac%7B9.8%20m%2Fs%5E2%5Ctimes%20T%5E2%7D%7B2%7D)
Solving for T, we gte :
T = 2.44 seconds
The mailbag will take 2.44 seconds to reach the ground.
It’s very small i can’t see it im sorry
