A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration of 2.30 m/s2. At 20.0 s after blastoff, the engines suddenly fail, and the rocket begins free fall. which means that the force they produce instantly stops.(a) How high above the launch pad will the rocket eventually go?(b) Find the rocket's velocity at its highest point.(c) Find the magnitude of the rocket's acceleration at its highest point.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
