Answer:
Correct answer: F = 214.56 N
Explanation:
Given:
V₀ = 0 m/s initial speed
V = 44.7 m/s speed after t = 29 seconds
m = 96 kg
F = ? horizontal force
Taking off an airplane is a uniformly accelerated motion to which the formula applies:
V = V₀ + a t and V₀ = 0 m/s
V = a t ⇒ a = V / t = 44.7 / 20 = 2.235 m/s²
a = 2.235 m/s²
the horizontal force is calculated using the formula:
F = m · a = 96 · 2.235 = 214.56 N
F = 214.56 N

Answer: W.D = 1/2mv^2
Explanation:
If an external force or a single force is acting on a body. Just like the first law of thermodynamics, the force acting on the body will cause work done on the system.
Work done = force × distance
And the work done on the body will cause the molecules of the body to experience motion and thereby producing kinetic energy.
The work done will be converted to kinetic energy.
W.D = 1/2mv^2
One double bond consists 4 electrons, so 2 double bonds means 8 electrons
