Answer:
5.5 km
Explanation:
First, we convert the distance from km/h to m/s
910 * 1000/3600
= 252.78 m/s
Now, we use the formula v²/r = gtanθ to get our needed radius
making r the subject of the formula, we have
r = v²/gtanθ, where
r = radius of curvature needed
g = acceleration due to gravity
θ = angle of banking
r = 252.78² / (9.8 * tan 50)
r = 63897.73 / (9.8 * 1.19)
r = 63897.73 / 11.662
r = 5479 m or 5.5 km
Thus, we conclude that the minimum curvature radius needed for the turn is 5.5 km
Answer:
B.
340meters per second x 2 seconds = 680 meters away
divided by 2coming back = 340
Hope this helps
Explanation:
Answer:
Scientific theories allow scientists to make predictions.
Answer:
The answer to your question is: B. F = 45 N
Explanation:
Newton's second law of motion states that the acceleration of an object is directly proportional to the force exerted and inversely proportional its mass.
Data
F = ?
a = 3 m/s²
m = 15 kg
Formula
F = ma
Process
F = ( 15)(3)
F = 45 N
