    [67 at the turning point is zero ; and to find (d), note tjiat on the return to the starting point the distance therefrom is zero.] Ans. (a) 22-5 cm.; (b) 700 cm.; (c) 112-5 cm.; (d) 3 sec. (6) A particle moves round a closed curve with a uniform rate of change of speed. In the mth, mth, and pth seconds, it describes a, b, and c circuits respectively. Show that, the initial speed being zero, a (n ~p) + b(p- m) + c (m - n) = 0. N.B.—The reader should solve the above problems also without using formulae. Others of a similar kind will be found in 141. 68. Case III.—The Rate of Change of Speed Variable. —Cases in which the rate of change of speed varies with the position of the moving point in its path can be dis- cussed with greater advantage at a later stage (see 158, 164).
