If a semi-truck decreases its speed from 10 m/s to 5 m/s, its new kinetic energy is:
Otrada [13]
Answer is: <span>1/4 its old kinetic energy .
</span>V₁ = 10 m/s.
V₂ = 5 m/s.
m₁ = m₂ = m.
E₁ = 1/2 · m₁ ·  V₁², E₁ = 1/2 · m · (10 m/s)² = 50 · m.
E₂ = 1/2 · m₂ · V₂², E₂ = 1/2 · m · (5 m/s)² = 12,5 · m.
E₂/E₁ = 12,5m / 50m = 0,25.
V - speed of semi-truck.
m - mass of semi-truck.
E - kinetic energy of semi-truck.

natali 33 [55]

Answer:

110.7 J

Explanation:

Hooke's law is represented by the formula:

F = ke  where F is the force in Newton, K is force constant and e is extension in m

work done = 1/2ke² = 1/2 K ( e² - e₀²) and e₀ is the extension at relaxed length

e₀ =0

work done = 0.5 × 82N/m × (2.70 m)² = 110.7 J

Which of the following does not contribute to Wellness
Tomtit [17]
<span>The option that does not contribute to wellness are tendencies. Tendencies are just things that you are more likely to do, or behavior that you are more likely to show, and in no way does that affect your wellness. However, your habits, exercise, and diet do, because all of these things have an impact on both your body and mind, thus creating a wellness of the entire human being.</span>

Which is more likely to be dangerous-a volcano that erupts frequently or a volcano that has been inactive for a hundred years? W
Korvikt [17]

Answer:

A volcano that erupts frequently.

Explanation:

Both.

But the volcano that hasn't erupted in 100 years would probably be more dangerous because you wouldn't be prepared for its explosion as you would be for the one that erupts frequently.

Glad I could help!!
