Question
A particle is moving with uniform acceleration along a straight line. Its velocities at A & B are respectively 7m/s & 17 m/s. M is mid point of AB. If t1 is the time taken to go from A to M and t2 the time take to go from M to B, the ratio 
is equal to : -
is equal to : -Options
A.3 : 2
B.3 : 1
C.2 : 1
D.2 : 3
Solution
vm2 = (7)2 + 2 × a × x ; vm = 13 m/s
(17)2 = (7)2 + 2 × a × 2x
= t1 ; t2 =
