Problem: (2 Parts) Consider a stick of mass, M = 14.0 kg and length, L = 1.60 m hanging vertically initially. A bullet of mass, m = 0.030 kg and speed, v = 70 m/s strikes and embeds itself at the bottom end of the stick. Magnitude of acceleration due to gravity is g = 10 m/s2. Note: The moment of inertia of a rod about it’s center of mass I = 1 12ML2. You may need to use the parallel axis theorem. 4 pt Part A: What is the angular speed, ω of the system (stick + bullet) just after the collision? 18.A 0.38 rad/s B 1.12 rad/s C 0.28 rad/s D 0.56 rad/s E None of the above

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

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

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
