Answer:
The speed of the particle is 2.86 m/s
Explanation:
Given;
radius of the circular path, r = 2.0 m
tangential acceleration, 
= 4.4 m/s²
total magnitude of the acceleration, a = 6.0 m/s²
Total acceleration is the vector sum of tangential acceleration and radial acceleration
where;
is the radial acceleration
The radial acceleration relates to speed of particle in the following equations;
where;
v is the speed of the particle
Therefore, the speed of the particle is 2.86 m/s
To throw an object into the space you need to throw it with the escape velocity of the earth which is 11.2 km/sec. therefore if you can throw an object with the speed of 11.2 km/sec it will leave the earth atmosphere and will reach to the space.

If im right give brainliest :)
The terrestrial planets are those that are similar to Earth. In Laint terra means Earth and Earth is Tierra.
The terrestrial planets have solid surface made up of rocks and metals.
There are four terrestrial planet in our planetary (solar) system: Mercury, Venus, Earth and Mars.
You can verify the sizes of those planets in many places.
Earth is the largest of the terrestrial planets.
Answer:
The gallon of milk is placed at a distance of 0.641 meters.
Explanation:
We have,
Mass of two 0.6 kg cartons of cereal is 1.2 kg
Length of the basket, l = 0.77 m
Center of the basket is 0.385 m
Mass of the half gallon of milk is 1.8 kg
Total weight in the basket is 1.2 + 1.8 = 3 kg
We need to find the position of the gallon of milk so that the center of mass (COM) of your groceries is at the center of the basket.
So,
(3 × 0.385) = (1.2 × 0) + (1.8 × x)
1.155 = 1.8 x
x = 0.641 meters
So, the gallon of milk is placed at a distance of 0.641 meters.
