Answer:</h3>
"<u>Therefore, the speed of the air decreases, the pressure acting on the two trains increases (by Bernoulli's principle), and the two trains lean in toward one another</u>."
Answer:
24N
Explanation:
Calculation for what his weight would be
Let his WEIGHT on the surface of earth be 600 and Let the RADIUS be 25 which is (5^²) because we were told that the radius is FIVE TIMES larger than earths
Now let calculate his weight using this formula
Weight=Weight on Earth/Radius
Let plug in the formula
Weight=600N/5^²
Weight=600N/25
Weight=24N
Therefore his weight would be 24N
Increasing a car's speed from 0 mph to 30 mph requires more work than that of 50 mph to 60 mph.
<h3>What is work?</h3>
Work is a measure of energy expended in moving an object. It is calculated by multiplying the force by the distance.
According to this question, work is required to move a car from one position to another.
The distance moved from 0 - 30mph is more than that moved from 50 - 60mph, therefore, increasing a car's speed from 0 mph to 30 mph requires more work than that of 50 mph to 60 mph.

Answer:
5 m/s
Explanation:
Work is force times distance.
W = Fd
Force is mass times acceleration.
W = ma d
Acceleration is change in velocity over change in time.
W = m Δv / Δt d
Distance over time is average velocity.
W = m Δv v_avg
W = m (v − v₀) (v + v₀) / 2
W = m (v² − v₀²) / 2
Plugging in values:
50 J = 4 kg (v² − (0 m/s)²) / 2
25 m²/s² = v²
v = 5 m/s
