Answer:
Heat flows from higher to lower temperature. So when you keep hot things in normal temperature, the heat from hot object transfers to the environment until they are both on the same level. Same happens when a cold object is kept in normal room temperature, the heat from the environment transfers to the cold object until they are both equal. its all about achieving the equilibrium in a system

It's actually a deceleration. You should get a negative answer because the ball is slowing down.
Givens
vi = 8.09 m/s
vf = 5.87 m/s
t = 9.17
Formula
a = (vf - vi) /t Substitute the givens into the formula
Solution
a = (5.87 - 8.09)/9.17
Answer
a = - 2.22 m/s^2
Answer:

Explanation:
While the satellite is in the space vehicle, it has the next potential energy

where G is the gravitational constant
m is the satellite's mass in kilograms
Me is the earth's mass
r is the orbit's radius from to the earth's center in meters


The additional energy required is the difference between this energy and the energy that the satellite would have in an orbit with an altitude of 22000 mi


Then
