(a) f in RI implies |f| in RI (b) |f| in RI implies f in RI (c) f in RI and 0 < c <= |f(x)| forall x implies 1/f in RI (d) f in RI implies f^2 in RI (e) f^2 in RI implies f in RI (f) f^
1. In a mechanical system, the displacement of a body, s meters, is related to time t seconds, by the integral: t = (integral) [r/(g +ks)]ds where r, g and k are all constants. Determine an expression in terms of r and k, for the time taken by the body to travel a distance g/k meters from its initial position.
