Answer:
a) 
b)
c)
Explanation:
a) Let's calculate the work done by the rocket until the thrust ends.

But we know the work is equal to change of kinetic energy, so:


b) Here we have a free fall motion, because there is not external forces acting, that is way we can use the free-fall equations.

At the maximum height the velocity is 0, so v(f) = 0.

c) Here we can evaluate the motion equation between the rocket at 25 m from the ground and the instant before the rocket touch the ground.
Using the same equation of part b)


The minus sign of 25 means the zero of the reference system is at the pint when the thrust ends.
I hope it helps you!
Answer:
Digestion
1 is correct since you need to eat something before anything else.
2 is incorrect since if this was first, what are you storing?
3 is incorrect since that is the second thing you need to do.
4 is incorrect since that is the last thing to do.
Given that the correct question is
Write Python expressions using s1, s2, and s3 and operators + and * that evaluate to: (a) 'ant bat cod'
Answer:
s1 = 'ant'
s2 ='bat'
s3 ='cod'
#using string concatenation
s4 = s1 + ' ' + s2 + ' ' +s3
print(s4)
