Answer:
The maximum safe speed of the car is 30.82 m/s.
Explanation:
It is given that,
The formula that models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature r r, is in feet is given by :
.........(1)
A highway crew measures the radius of curvature at an exit ramp on a highway as 380 feet, r = 380 feet
Put the value of r in equation (1) as :
v = 30.82 m/s
So, the maximum safe speed of the car is 30.82 m/s. Hence, this is the required solution.
Answer:
the moment of inertia of this system of masses about the y-axis is 99 kgm²
Explanation:
Given the data in the question;
mass m₁ = 5.0 kg at point ( 3.0, 4.0 )
mass m₂ = 6.0 kg at point ( 3.0, -4.0 )
Now, Moment of inertia of this system of masses about the y-axis will be;
Moment of inertia ₓ = mixi²
Moment of inertia = m₁x₁² + m₂x₂²
we substitute
Moment of inertia = [ 5.0 × ( 3 )² ] + [ 6.0 × ( 3 )² ]
Moment of inertia = [ 5.0 × 9 ] + [ 6.0 × 9 ]
Moment of inertia = 45 + 54
Moment of inertia = 99 kgm²
Therefore, the moment of inertia of this system of masses about the y-axis is 99 kgm²
