Answer:
Ratio of length will be
Explanation:
We have given time period of the pendulum when length is is
And when length is time period
We know that time period is given by
So ----eqn 1
And -------eqn 2
Dividing eqn 2 by eqn 1
Squaring both side
Answer:
4.14°
Explanation:
given:
r = 1.2 km
v = 105 km/h
1) <em>convert your given </em>
a) r = 1.2 km to m = 1200m
b) v = 105 km/h to m/s = 29.2 m/s
2) <em>plug into your ideal banking angle equation</em>
(
) =
= 4.14°
