The velocity of a particle moving along the x axis is given by v=[tex]x^{3}[/tex]-4[tex]x^{2}[/tex]+7x whwere x is in meters and v in m/s. determine the acceleration when x=5m...(adsbygoogle = window.adsbygoogle || []).push({});

the thing i know is that i just can't differentiate v to get y, since it is a function of x..

i dont know if chain rule would work..and i dont know how to do it..

Thanks in advance!
