I have a question that appears elementary, but bizarre in its conclusion:(adsbygoogle = window.adsbygoogle || []).push({});

A mass ##M## is accelerated by a spring of length ##L##, wave-speed ##v_p##, spring-constant ##K## and a constant force ##F## at the other end. As ##K## increases, the extension of the spring ##dx## decreases as does the energy stored ## \frac{1}{2} k{dx}^2 ##. The max rate at which work can be done by the spring on the mass is of the order:

##P## = (energy stored in spring)/(propagation time over spring's ##L##)

= ## \frac{1}{2} k{dx}^2v_p/L ##

Hence as ##K\rightarrow \infty, P \rightarrow 0##: the mass can't accelerate!

Is this correct?

The physics seems to say yes, but I don't quite believe it and may have gone wrong somewhere.

# I Acceleration of mass depends upon K and L of a spring?
