Question

Two horizontal curves on a bobsled are banked at the same angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius curve v. What is the safe speed on the larger radius curve?
A)approximately .707v
B)approximately 1.41v
C)2v
D).5v

Answer 1

Answer 2

safe speed for a banked curve:
\[v_{\rm max}=\sqrt{rg\tan\theta}\]

Answer 3

g and theta are same and "r" changes
take the ratio

Answer 4

ok thank you so much for that
