Answer:
23.99N
Explanation:
Given:
Pressure created by the heart = 120mm of hg
converting the pressure into the standard unit of N/m²
1mm of hg =
now, 120 mm of hg in N/m² will be
120mm of hg =
also
given effective area = 15.0 cm² = 15 × 10⁻⁴m²
Now,
Force = Pressure × Area
thus,
Force exerted will be = × 15 × 10⁻⁴m²
or
Force exerted will be = 23.99N
Answer:
= 10.3 m/s
Explanation:
We can solve this exercise using the conservation of the moment; the system is formed by the knife and the target, with an isolated system the moment is conserved during the collision
Knife mass m = 22.5 g and its velocity v₁₀ = 39 m / s, the mass of white is M = 300 gr and its velocity is v₂₀ = -2.15 m / s
Before the crash
p₀ = m v₁₀ + M v₂₀
After the crash
= m v₁ₐ + 0
p₀ =
m v₁₀ + M v₂₀ = m
= (m v₁₀ + M v₂₀) / m
Let's calculate
= (0.0225 39.0 + 0.300 (-2.15)) / 0.0225
= 10.3 m / s
