Question

A uniformly accelerated body travelling along a straight line with an initial velocity of 2 m/s passes over 24 m from start in 3 seconds. Calculate the acceleration and the velocity it will acquire when it has passed over 4 m from the start

Answer 1

s=ut+(1/2)at^2

24=2×3+(1/2)a×9

a=4 m/s^2

v^2=u^2+2as'

v^2=4+2×4×4

v=6 m/s
