D

Abby I see you post these questions a lot, do you take any time to try to learn them/ think about them? if it can accelerate 5.1 m/s^2 in only one second, how could it be any other answer other than D? the rest are less than 5 even.

linear displacement of a particle with time is given by 
s=ut +1/2at^2
u->initial velocity
since u=0
s=1/2at^2
s=1/2*5.1*1.5*1.5

Yeah, actually. 
i'm studying for finals so im going over which is why there are so many questions. 
thanks for so being concerned. @robertsn
& thanks @MayankD for helping and not taking time to figure out what I learn.

anonymous · Answer

& is s=ut+1/2at^2 always the equation for linear displacement? @MayankD

:) here to help

yes only when the accleration is constant in magnitude and direction
