1.	A particle moving along a straight line with uniform acceleration, passes successively through three points A, B, C. If t1 = time taken to go from A to B; t2 = time taken to go from B to C and AB = a, BC = b, then what is the value of acceleration?
A.	2(bt1 – at2)/t1t2(t1 + t2)
B.	-2(bt1 – at2)/t1t2(t1 + t2)
C.	2(bt1 + at2)/t1t2(t1 + t2)
D.	2(bt1 – at2)/t1t2(t1 – t2)
Answer» B.
