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  : -

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 =
