Answer:
The man's velocity relative to the moving walkway is, v₂₃ = 0.2 m/s
Explanation:
Given data,
The speed of the moving walkway, v₁₂ = 0.9 m/s
The speed of the man walking on a walkway to the stationary observer, v₁₃ = 1.1 m/s
The speed of the man walking on a walkway to the walkway, v₂₃ = ?
The formula for relative velocity is,
<em> v₁₃ = v₁₂ + v₂₃</em>
∴ v₂₃ = v₁₃ - v₁₂
Substituting the values,
v₂₃ = 1.1 - 0.9
= 0.2 m/s
Hence, the man's velocity relative to the moving walkway is, v₂₃ = 0.2 m/s
Answer:
sorry about the other person but its b
Explanation:
To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.
The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,
Equating both equation we have that,
Rearranging to find the angle we have that,
Our values are given as,
Therefore the minimum angle will be 11.53°
