Answer:
The radius of curvature is 979 meter
Explanation:
We have given velocity of the canon ball v = 98 m/sec
Acceleration due to gravity
We know that at highest point of trajectory angular acceleration is equal to acceleration due to gravity
Acceleration due to gravity is given by , here v is velocity and r is radius of curvature
So
r = 979 meter
So the radius of curvature is 979 meter
Answer:
Grade is 10.32%
Explanation:
Given data:
stopping side distance is 800ft
t = 2.5 sec
design speed v = 65 miles/hr
a/g value is 0.35
stopping side distance is SSD
plugging all value for G
G = 0.1032
Grade is 10.32%
