The banking angle of the curved part of the speedway is determined as 32⁰.
<h3>
Banking angle of the curved road</h3>
The banking angle of the curved part of the speedway is calculated as follows;
V(max) = √(rg tanθ)
where;
- r is radius of the path
- g is acceleration due to gravity
V² = rg tanθ
tanθ = V²/rg
tanθ = (34²)/(190 x 9.8)
tanθ = 0.62
θ = arc tan(0.62)
θ = 31.8
θ ≈ 32⁰

#SPJ1
Divide (25,000) by (the number of miles you can walk in 1 hour).
The answer you get is the number of hours it would take you to walk around the Earth once, IF you were able to walk on water too.
Answer:
1.30
Explanation:
To calculate the critical angle we have ti use the formula:
where theta_c is the critical angle, n1 is the index of refraction of the material where the light is totally reflected, and n2 is the refractive index of the other material.
By taking n_2 and replacing we obtain:
hope this helps!!
Answer:
Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (beginning speed)
= (3,600 mi/hr) - ( 0 )
= 3,600 mi/hr
= same as 1 mile/second.
Acceleration = (1 mi/sec) / (10 sec)
= 0.1 mi/sec² .
But 1 mile = 5,280 ft,
so
0.1 mi/s² = 528 ft/s²
