Question

What is the minimum banking angle for an Olympic bobsled to negotiate a 100-m radius turn at 35 m/s without skidding?

1) 30°
2) 45°
3) 51°
4) 60°

Answer 1

The minimum banking angle for an Olympic bobsled to negotiate a 100-m radius turn at 35 m/s without skidding can be calculated using the formula: θ = tan^-1(v^2 / (g * r)).

Step-by-step explanation:

The minimum banking angle for an Olympic bobsled to negotiate a 100-m radius turn at 35 m/s without skidding can be calculated using the formula:

θ = tan-1(v2 / (g * r))

Where:
θ is the banking angle in degrees
v is the speed in m/s
g is the acceleration due to gravity (approximately 9.8 m/s²)
r is the radius of the turn in meters

Plugging in the given values:
θ = tan-1((352) / (9.8 * 100))

Calculating this expression will give us the minimum banking angle.
