The speed downwards is 7 + (3*9.8)
7+ 29.4 = 36.4 m/s
Velocity
Because velocity is speed with direction. In this scenario, the speed has not changed, but the direction did.
Answer:
33.65°
Explanation:
radius, r = 53.1 m
m = 2.9 Mg = 2.9 x 10^6 g = 2900 kg
v = 67 km/h
convert km/h into m/s
v = 18.61 m/s
Let the angle of banking of road is θ, without friction


tan θ = 0.6655
θ = 33.65°
Thus, the angle of banking of road is 33.65°.
