A) \[14.0\,\,m/s\]
B) \[140\,\,m/s\]
C) \[1.4\,\,m/s\]
D) \[9.8\,\,m/s\]
Correct Answer: A
Solution :
Given\[\mu =0.2\] \[g=9.8\,\,m/{{s}^{2}}\] \[r=100\,\,m\] Maximum velocity with which the cyclist can take a circular path of radius \[r\] is \[v=\sqrt{\mu rg}\] So,\[v=\sqrt{0.2\times 100\times 9.8}\] \[=\sqrt{196}=14\,\,m/s\]You need to login to perform this action.
