A rocket is launched straight up with constant acceleration. 4 seconds after liftoff, a bolt falls off the side of the rocket. The bolt hits the ground 6.10s later. What was the rocket's acceleration?(adsbygoogle = window.adsbygoogle || []).push({});

rocket: xfinal = 1/2a^2 x 4s^2

bolt: vfinal = 0+ -9.9 m/s^2 * 2.1s

given this vfinal, of -20.58 m/s, then x = 21.61 for distance traveled

using 21.61 for the rocket, 21.61=1/2a(4s)^2

a = 2.7m/s^2

This isn't the correct answer. Could you please show me how to set this problem up? HELP.

Thanks.
