Question

A body is moving with constant acceleration,
a = 5 m/s² from A to B in straight line AB. The
velocity of particle at A and B are 5 m/s and 15 m/s respectively. The velocity at mid-point of AB is
(1) √125 m/s (2) √250 m/s
(3) √550 m/s (4) √600 m/s​

Answer 1

v =√(15)^2 +(5)^2

v = √225+25

v =√250

v=5√10.
