2.22 m/s. Average speed is Total distance over time it took. 100m/45s = 2.22m/s
Answer:
a is the answer I think so
Answer:
the banking angle of the road is 24.2⁰
Explanation:
Given;
speed of the vehicles considered, v = 75 mi/h
Speed in m/s ⇒ 1 mi/h --------> 0.44704 m/s
75 mi/h --------> ?
= 75 x 0.44704 m/s = 33.528 m/s
radius of the curve, r = 255 m
The banking angle of the road is calculated as;

Therefore, the banking angle of the road is 24.2⁰
