Two particles, A and B start moving from the same point at the same time. Particle A moves 108 cm on the first second, 104 cm on the second second, 100 cm on the third second and this is continued. Particle B moves y cm on the first second and reduces 2 cm for each subsequent seconds. Both of them stop at n seconds. Calculate, (i) the value of n
(ii)the value of y
(iii) the difference between the distance travelled by particles A and B when they stopped.
