Question 17

(a) Forces F," [-:] N, F, "[:]N, F, f,]N and F. -[ .:] N act on body. Find the:

(i) resultant of these forces;

(ii) fifth force that will keep the system in equilibrium.

_____________________________________________________________________________________________________
Observation

A body, moving at 20 ms accelerates uniformly at 2.5 ms for 2 seconds, It continues
the journey at this speed for 8 seconds, before coming to rest t seconds with a uniform   retardation. If the ratio of acceleration to retardation is 3:4                

The (a) part was satisfactorily handled by the few candidates that attempted it but the (b) part was badly handled. They were expected to sketch the velocity - time graph and use it to calculate.the total distance covered. Very few candidates were able to do this.
