2. The electric motor of a model train accelerates the train from rest to 0.502 m/s in 20.0 ms. The total mass of the train is 825 g. Find the average power delivered to the train during its acceleration.

use guess method as mention below if you cant use it dont do the question at all please do it in guss method no other way    Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work. This part is very important, since you will…

For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?

Responses should be as simple as possible, and in typed form, with all applicable units, following a clear and straightforward logical structure. NO hand-drawn explanations are allowed. Ensure the appropriate use of significant figures, and when applicable, employ the "variable space" framework for providing answers.
