Answer:
2.5 x 10⁷ J
Explanation:
F = thrust of the engine = 2.3 x 10⁵ N
d = distance traveled = 87 m
Work done by the engine is given as
W = F d = (2.3 x 10⁵) (87) = 200.1 x 10⁵ J
W' = Net work done
W'' = work done by catapult
KE₀ = initial kinetic energy = 0 J
KE = final kinetic energy = 4.5 x 10⁷ J
Net work done is given as
W' = KE - KE₀
W' = 4.5 x 10⁷ J
We know that
W' = W + W''
4.5 x 10⁷ = 2.001 x 10⁷ + W''
W'' = 2.5 x 10⁷ J
Answer:

<h3>
I HOPE ITS RIGHT IF NOT THEN SORRY</h3>
HAVE A GREAT DAY :)
Answer: C
Explanation: Convert 50 km to m, and you get 50,000. You then divide by 14 and get 3,571.42....The closest answer is C
Answer:
From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star.
