Im having a problem with this question, which is probably rather simple but I am making a lot harder than it needs to be.(adsbygoogle = window.adsbygoogle || []).push({});

A high-speed train is traveling at 44.72m/s and it sees a sidecar a distance of 676m ahead. The sidecar is traveling with a constant velocity or 8.056m/s.

The question asks what the magnitude of the resulting constant deceleration must be if a collision is to be just avoided.

I took two of the derived C.A. equations and in each one had two unknowns which were x(final) and t.

I then equated the two equations and solved the linear system for t at which I arrived with an answer of 47.26s

From there it is quite easy to figure out the rest of the question, but I am not sure if I am doing this question the best way or even correctly for that matter.

Any suggestions or comments would be greatly appreciated
