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°
Answer:
2.72×10^-7
Explanation:
velocity = frequency × wavelength
2.05×10^8=7.55×10^14 wavelength
wavelength = 2.05×10^8/7.55×10^14
wavelength = 2.72×10^-7

Answer: 2 s
Explanation: In order to solve this problem we have to use the formule of the final speed getting with a constant acceleration, it is given by;
Vfinal=Vo+a*t where Vo is zero.
so then t=Vfinal/a = (10 m/s)/5 m/s^2= 2 s
