Answer:
v₂ = 63.62 m / s
Explanation:
For this exercise in fluid mechanics we will use Bernoulli's equation
P₁ + ρ g v₁² + ρ g y₁ = P₂ + ρ g v₂² + ρ g y₂
where the subscript 1 refers to the inside of the wing and the subscript 2 to the top of the wing.
We will assume that the distance between the two parts is small, so y₁ = y₂
P₁-P₂ = ρ g (v₂² - v₁²)
pressure is defined by
P = F / A
we substitute
ΔF / A = ρ g (v₂² - v₁²)
v₂² =
suppose that the area of the wing is A = 1 m²
we substitute
v₂² =
v₂² = 79.10 + 3969
v₂ = √4048.1
v₂ = 63.62 m / s
Answer:
The average angular acceleration is
Explanation:
From the question we are told that
From the question we are told that
The length of the bat is \
The initial linear velocity is
The time is
The velocity at t is
Generally average angular acceleration is mathematically represented as
Where is the finial angular velocity which is mathematically evaluated as
and is the initial angular velocity which is zero since initial linear velocity is zero
So
