Answer:
5 meters per second squared
Explanation:
We calculate the acceleration using the formula:
a = (vf - vi) / t
where "vf" is the final velocity, "vi" the initial velocity, and "t" the time it took to change from the initial velocity to the final one.
In our case:
a = (45 - 5) / 8 = 40 / 8 = 5 m/s^2

The minimum thickness is
Answer:
there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
When you do work to lift the object, the amount of work you do BECOMES the object's gravitational potential energy. It GETS its potential energy from the work you do to lift it. They're equal. You lose it, and the object gains it. Energy is not created or destroyed. It's just transferred from you to the object.
Later, when you DROP the object, GRAVITY does the same amount of work on it, to pull it to the ground. Again, no energy is created or destroyed. Every time a force acts to move anything, the energy to do it comes from somewhere, and the energy goes somewhere.
Answer: A
Explanation: How large a parachute is (in other words, the parachute's surface area) affects its air resistance, or drag force. ... In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
