The problem statement, all variables and given/known data The question is: The velocity of a particle is given as a function of its position s: v = (A - 4 s2)1/2 where s is displacement (in m), and v is velocity (in m/s). A is a constant but you do not need to know its value to answer this question. What is the acceleration (in m/s2) when s is as given below? S=1.9m The attempt at a solution i have tried integrating using the fact that v=ds/dt this gets 1/((A - 4 s2)1/2)ds=dt. I integrated first by using partial fractions then using the fact that 1/(A2-x2)1/2=arcsin(x/a) However whatever i do i end up with the constant A still in there??
