Answer:
85.14 m
Explanation:
Let g = 9.81 m/s2. We can find the truck mass from its weight
m = W/g = 14000 / 9.81 = 1427 kg
So if the maximum friction could be the truck weight, which is F = 14000N, then that would also be the maximum centripetal force it could be. According to Newton 2nd law of motion, the maximum centripetal acceleration the truck can have when traveling at a curve is
a = F / m = 14000 / 1427 = 9.81 m/s2
By applying the following formula we can find the minimum safe radius R of the curve when traveling at speed of 28.9 m/s
