A man running with a uniform velocity u on a straight road sees a bus just starting when it is at a distance x from him. If the acceleration of the bus is f, then what is the maximum possible value of x that would enable the man to catch the bus?
1
There is no upper limit
2
\(\frac{{{u^2}}}{{4f}}\)
3
\(\frac{{{u^2}}}{f}\)
4
\(\frac{{{u^2}}}{{2f}}\)
