That's false. Both moons of Mars are tiny, and Mercury and Venus have no moons at all.
time taken by the object dropped = 2s
this time depends on the height of the plane from ground
it is given by
![h = \frac{1}{2} gt^2](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20gt%5E2)
now the distance covered horizontally is given as 190 m
now the speed of the object is
![v = \frac{190}{2} = 95 m/s](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B190%7D%7B2%7D%20%3D%2095%20m%2Fs)
now when plane is moving at same height but with double speed
so it will take same time to hit the ground again
so the time is given as
![t = 2 s](https://tex.z-dn.net/?f=t%20%3D%202%20s)
so it will take t = 2 s again to hit the ground
Answer:
16.6N
Explanation:
Given parameters:
Mass of rocket = 2000g = 2kg
Acceleration = 8.3m/s²
Unknown:
Force acting on the rocket = ?
Solution:
The force acting on a body can be derived from the product of its mass and acceleration;
Force = mass x acceleration
Insert the parameters and solve;
Force = 2 x 8.3 = 16.6N
