Answer:
V = 25.3 , θf = 36.7° below the horizontal
Explanation:
Given Vo = 22m/s , θ = 23°
Vx = VoCosθ
Vy = VoSinθ – gt
t = total time of flight
F = m . g = 76.5 x 9..8 = 749.7
Net Force = 3225 - 749.7 = 2475.3
F = m.a
2475.3 = 76.5 a
a = 32.35
V = at + v1
V = at + 0
V = 32.35 x 0.15
V = 4.8525
Hope this helps
Answer: lift force = 100sin60 = 86.6 N
pull force = 100sin60 = 50.0 N
Explanation:
Hydrogen gas is harmless to your feet so since you don’t need protection against it that seems the best answer.
Answer:Principle of rectilinear propagation of light
Explanation:Principle of rectilinear propagation of light
Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. ... It is because light travels along a straight line and leaves only the areas where the object interferes.
